Abstract:
Unbalanced use of chemical fertilizer is a problem in the intensive cropping systems on the Northern part of Bangladesh. Proper nutrient management is essential to maximize maize production and sustain agricultural production while minimizing negative impacts on the soil fertility. The aim of the present study was to investigate nutrient dynamics, maize yields and soil fertility in response to balanced fertilization. A field experiment (2009–2010) was conducted at FSRD site Lahirirhat, OFRD, Rangpur during rabi season 2009-2010 to evaluate Maximizing maize production through nutrient management. Five treatments viz.T1= N300P50K150S30, T2=P50K150S30, T3= N300K150S30, T4= N300P50S30 and T5= N300P50K150were evaluated for this purpose. The result indicated that the highest grain yield (8.37 t/ha) was found from T1= N300P50K150S30 treatment. The lowest grain yield (7.33 t/ha) was obtained from T2=P50K150S30 treatment. The gross return (Tk.100107/ha) and gross margin (Tk.44951/ha) was higher with T1 and T3 treated plot. It may be concluded that proper nutrient management may be the good alternatives for maximizing maize yield and management of soil health at Rangpur region in Bangladesh.Progressive Agriculture 27 (4): 428-434, 2016

Abstract:
A 3-yr study was conducted on nine farms across southern Ontario to evaluate the risks and benefits of different approaches to weed management in corn and soybean. Weed control decisions were based on field scouting and recommendations from the Ontario version of HADSS™, the herbicide application decision support system. Treatments were selected to maximize profit (economic threshold approach) or to maximize yield (highest treatment efficacy). Reduced rates of the high efficacy treatment for each field also were included. Weed density before and after treatment, crop yields, weed seed return, and the effect of weed control decisions on weed density 1 yr after treatment were assessed. Crop yield varied among years and farms but was not affected by weed control treatment. Weed control at 28 d after treatment (DAT) was often lower and weed density, biomass, and seed production 70 DAT were often higher with the profit maximization approach compared with the yield maximization approach. However, weed density 1 yr later, after each cooperator had applied a general weed control program, did not vary significantly among the previous year's weed control treatments. Reduced rates of the high efficacy treatments did not lead to increased weed problems the next year, despite lower weed control and increased weed seed production in some years. During the 3 yr of the study, weed control costs with the profit maximization approach were approximately Can$45/ha less than with the yield maximization approach.

Abstract:
The objective of this work was to evaluate the yield of calyxes of Hibiscus sabdariffa L, a medicinal plant, at four planting times in Lavras - MG. The treatments were four planting times (October 18th, November 15th, December 18th 2001 and January 15th 2002) and a harvest was proceeded when practically there were no developing calyxes, almost at the end of the plant cycle. The numbers of calyxes per plant, the fresh and dry biomasses of calyxes and quality were taken into account. It follows that planting time influenced yield per plant and the fresh and dry biomasses of calyxes, differing from each other by Tukey test at 5%. In October planting, there was a higher yield (2,522kg/ha) with a yield 5.24 as high relative to the planting of the month of January (481 kg/ha). The planting s in the month of November to December showed yields of 1,695 and 1,093 kg/ha of dry calyxes, respectively and in relation to the same months of January, yield was of 3.52 to 2.27 times more. Harvest must be done as soon as the calyxes are ripe in order to preserve quality.

AbstractHeyman's model, paradoxically, predicts that whereas a maximizing approach to drug choice will prevent escalation of drug use it will never yield complete abstinence. We suggest an alternative model that overcomes this difficulty by focusing on changes in drug tolerance. A small modification allows maximization to predict either abstinence or moderation (e.g., social drinking).

Abstract:
The concept of crop yield maximization has been widely supported. In practice, however, yield maximization does not necessarily lead to maximum socioeconomic welfare. Optimization is therefore necessary to ensure quality of life of farmers and other stakeholders. In Thailand, a rice farmers' network has adopted a promising agricultural system aimed at the optimization of rice farming. Various feasible techniques were flexibly combined. The new system offers technical strengths and minimizes certain difficulties with which the rice farmers once struggled. It has resulted in fairly good yields of up to 8.75 t ha−1or yield increases of up to 57% (from 4.38 to 6.88 t ha−1). Under the optimization paradigm, the farmers have established diversified sustainable relationships with the paddy fields in terms of ecosystem management through their own self-motivated scientific observations. The system has resulted in good health conditions for the farmers and villagers, financial security, availability of extra time, and additional opportunities and freedom and hence in the improvement of their overall quality of life. The underlying technical and social mechanisms are discussed herein.

Abstract:
The experiment was conducted at Agronomy field of Bangladesh Agricultural Research Institute, Gazipur during 2016-2017 and 2017-2018 to determine the nutrient requirement for yield maximization of Bt brinjal (var. BARI Bt Begun-2). The treatments were T1= STB (soil test base) recommendation (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure), T2 = T1 + 25% of N-P-K-S-Zn-B (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T3= T1 + 50% of N-P-K-S-Zn-B (180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T4= T1 + 25% of N-P-K-S-Zn-B + 3 t/ha poultry manure (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B+6 t/ha poultry manure), T5= T1 + 3 t/ha poultry manure (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B + 6 t/ha poultry manure). Nutrient uptake, yield components and yield of Bt brinjal varied significantly due to variation of nutrients in the tested years. The highest plant height (98-116 cm), canopy coverage (1.21-1.26 m2/plant), number of fruits/plant (57.69-59.23) and individual fruit weight (83-86 g) were obtained from 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure (T3) treatment where days to flowering showed the lowest values (109-110 days). The highest pooled yield (58.46 t/ha) of Bt brinjal was observed from the treatment 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure(T3) and the lowest (23.39 t/ha) from 120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure) (T1). The highest nutrient uptake (214-43-208-60-0.38-0.213-49 kg/ha N-P-K-S-B-Ca) was also observed from the same treatment (T3). Fruit yield showed a strong (r=0.97) linear relationship with applied nutrients. Effect of nutrient application on fruit yield of Bt brinjal was estimated about 86%. The highest gross return (Tk. 587900/ha), gross margin (Tk. 417660/ha) and benefit cost ratio (3.45) were obtained by applying 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B+3 t/ha poultry manure. Results revealed that application of 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B along with 3 t/ha poultry manure would be economically optimum for achieving higher yield of Bt brinjal grown under Grey Terrace soil (Aeric Albaquept) of Gazipur.

Abstract:
An experiment was conducted in 2017 at Alwaha Project, Khartoum State to study the potential of ethanol yield from fermented juice of local and exotic sweet sorghums. 40 genotypes were arranged in RCB design. Juice yield, ethanol yield as percentage of fermented juice, actual and theoretical ethanol yields were studied. The Baker’s yeast (Saccharomyces cerevisiae) was used in the fermentation process. ANOVA tests, correlation and regression analysis of actual vs theoretical ethanol yield were performed. Significant differences were detected among genotypes for ethanol yields. High ethanol yields as percentage from fermented juice were obtained, but ethanol yield per hectare was relatively low due to low juice yields. The genotypes BlueRibbon and KensasCollies from exotic materials; 5AbjSG51 and S.154 Ab70 from local materials were identified as promising for ethanol production. Correlation between actual ethanol yield and Juice yield was positive and highly significant. Regression analysis indicated that theoretical ethanol yield was little bit overestimated. It was concluded that juice yield is more crucial than ethanol concentration in maximizing ethanol yield of sweet sorghum. More efforts are needed to develop high juice-yielding genotypes. Juice maximization can also be achieved by using efficient milling devices and optimizing cultural practices.

Abstract:
Yield maximization is an important aspect in the design of integrated circuits. A prerequisite for its automation is a reliable and fast worst performance analysis which results in corners that can be used in the process of circuit optimization. We formulate the constrained optimization problem for finding the worst performance of an integrated circuit and develop a direct search method for solving it. The algorithm uses radial steps and rotations for enforcing the inequality constraint. We demonstrate the performance of the proposed algorithm on real world design examples of integrated circuits. The results indicate that the algorithm solves the worst performance problem in an efficient manner. The proposed algorithm was also successfully used in the process of yield maximization, resulting in a 99.65% yield.

Abstract:
Microalgae has received overwhelming attention worldwide as a sustainable source for energy generation. However, the production of biofuel from microalgae biomass consists of several steps, of which lipid extraction is the most important one. Because of the nature of feedstock, extraction needs special attention. Three different methods were studied to extract algal oil from two different algae variant, Chlorella sp. and Spirulina sp. The highest percentage oil yield was obtained by ultrasonication (9.4% for Chlorella sp., 6.6% for Spirulina sp.) followed by the Soxhlet and solvent extraction processes. Ultrasonication and Soxhlet extraction processes were further optimized to maximize oil extraction as solvent extraction was not effective in extracting lipid. For ultrasonication, an amplitude of 90% recorded the highest percentage yield of oil for Spirulina sp. and a 70% amplitude recorded the highest percentage yield of oil for Chlorella sp. On the other hand, for Soxhlet extraction, a combination of chloroform, hexane, and methanol at a 1:1:1 ratio resulted in the highest yield of algal oil. Afterward, the crude algae oil from the ultrasonication process was transesterified for 5 h using an immobilized lipase (Novozyme 435) at 40 °C to convert triglycerides into fatty acid methyl ester and glycerol. Thus, ultrasonic-assisted lipid extraction was successful in producing biodiesel from both the species.

Full text
Abstract:
A mixed-species yield-per-recruit model is developed for a portion of the Oregon flatfish fishery. The model is applied to examine the effects of implementing various management policies on fishery yield in weight and revenues for Pacific Marine Fisheries Commission Area 2B. Three types of management policies are considered: maximization of output, efficiency-oriented, and a minimum trawl cod-end mesh size regulation with no restriction of effort. If an efficiency-oriented policy were adopted, the current minimum mesh size regulation of 114 mm would be optimal. However, if effort is left unrestricted, or if a maximization strategy were adopted, a larger mesh size would result in greater volume yields. Optimal mesh size is more sensitive to the management policy selected than it is to either variations in recruitment or to costs associated with fishing. If economic considerations become more important in formulating management policy, greater gains could be achieved by limiting effort than by altering mesh size regulations. However, as the management policy becomes less restrictive of effort, the influence of mesh size on fishery output increases.

Abstract:
This study examines the relationship between foliar nitrogen:potassium (N:K) ratio and in-shell yield of pecan [Carya illinoinensis (Wangenh.) K.Koch]. Regression analysis of linear and curvilinear relationships between leaflet N:K ratio and in-shell yield identified associations relevant to orchard nutrition management. Analysis revealed that ON (heavy crop) year N:K ratio correlates with ON year yield (r2 = –0.69), OFF (light crop) year yield (r2 = +0.34), 2-year average yield (r2 = −0.52), and difference between ON and OFF year yields (r2 = –0.69) below the optimum yield level (less than 1800 kg·ha−1) for southeastern U.S. pecan orchards. Pecan yield therefore appears to be associated with N:K ratio. This study suggests that a decline in pecan yield is associated with high N:K ratios in the ON year, thus meriting further investigation into the relationships of N and K to yield. It is suggested that pecan orchards be managed such that foliage contains a N concentration of 2.5% to 2.9% and a K concentration of 1.3% to 1.5% while maintaining the N:K ratio at ≈2:1 for maximization of pecan yields in the southeastern United States over the long term.

We study a stochastic control approach to managed futures portfolios. Building on the (Schwartz, 1997) stochastic convenience yield model for commodity prices, we formulate a utility maximization problem for dynamically trading a single-maturity futures or multiple futures contracts over a finite horizon. By analyzing the associated Hamilton–Jacobi–Bellman (HJB) equation, we solve the investor’s utility maximization problem explicitly and derive the optimal dynamic trading strategies in closed form. We provide numerical examples and illustrate the optimal trading strategies using WTI crude oil futures data.

Abstract Lleonart, J., and Merino, G. 2010. Immediate maximum economic yield; a realistic fisheries economic reference point. – ICES Journal of Marine Science, 67: 577–582. Unregulated or poorly managed fisheries tend towards overexploitation, but fisheries rent does not completely dissipate when immediate rent maximization is sought. The principle of immediate economic rent maximization is the basis of the derivation of a classic model and has led to the definition of a relationship in a catch-and-effort diagram termed the dynamic immediate maximum economic yield (DIMEY) curve. For any initial biomass, if the economic rent in the immediate fishing season is maximized, then the fishing effort and catch strategy that follows will be located on the DIMEY curve. The DIMEY curve is not only used for dynamic simulation but also used to identify a new reference point, the immediate maximum economic yield (IMEY), which is proposed as more realistic than the classic open-access solution for unregulated fisheries. IMEY is proposed as an asymptotic outcome for unregulated or poorly managed fisheries when short-term economic objectives drive fleet activities. IMEY properties are described and compared with traditional fisheries reference points in the yield-and-effort diagram. Theoretical conclusions are compared with empirical evidence provided by the red shrimp fishery off Blanes, Spain (NW Mediterranean). Observed catch-and-effort records are plotted and were positively correlated with the DIMEY curve and IMEY.

Full text
Abstract:
Disease and yields of peanut were monitored in growers' fields treated with zero, one, two, three, and four applications of tebuconazole. Yields ranged from 1,918 to 6,891 kg/ha and averaged 4,319 kg/ha over eight locations in 3 study years. Defoliation caused by peanut leaf spots (Cercospora arachidicola and Cercosporidium acutatum) and incidence of southern stem rot (Sclerotium rolfsii) were inversely related to number of tebuconazole applications, while yield was directly related to number of tebuconazole applications. Average yields with zero, one, two, and four tebuconazole applications (each application at 0.25 kg a.i./ha) were 3,609, 4,088, 4,526, and 4,868 kg/ha, respectively. Data from each location were best modeled by quadratic equations allowing determination of numbers of tebuconazole applications for minimal disease and maximal yields. Calculated spray numbers indicate that between three and four applications of tebuconazole is best for disease control and yield maximization.

Abstract:
In this paper we propose a fuzzy co-clustering algorithm via modularity maximization, named MMFCC. In its objective function, we use the modularity measure as the criterion for co-clustering object-feature matrices. After converting into a constrained optimization problem, it is solved by an iterative alternative optimization procedure via modularity maximization. This algorithm offers some advantages such as directly producing a block diagonal matrix and interpretable description of resulting co-clusters, automatically determining the appropriate number of final co-clusters. The experimental studies on several benchmark datasets demonstrate that this algorithm can yield higher quality co-clusters than such competitors as some fuzzy co-clustering algorithms and crisp block-diagonal co-clustering algorithms, in terms of accuracy.

Abstract:
More efficient water management practices need to be adopted for better sustainable rice production grown under traditional areas due to increased water scarcity. Among the different water management practices, efficient new generation water-saving chemicals and organic products were used to conserve water under field condition. An experiment was conducted to evaluate the yield maximization in direct sown CO51 rice (Oryza sativa L.) under water constraint situation. The main plot treatments comprised of three levels of irrigation viz., Conventional irrigation (M1), Tensiometer based irrigation (M2) and Deficit irrigation (M3), respectively and were tested with four different water conservation practices in sub-plots viz., soil application of water-saving crystals (WSC) @ 5 kg ha-1 (S1), foliar application of drought shield @ 3 litres ha-1 (S2 ), soil application of humic granules @ 2.5 kg ha-1 (S3) and soil application of FYM @ 12.5 t ha-1 (S4). Experimental results indicated that Tensiometer based irrigation with soil application humic granules @ 2.5 kg ha-1 M2S3) recorded higher number of panicles m-2 (411) and number of filled grains panicle-1 (108.16) in direct-sown rice. However, M2S3 recorded significantly maximum grain yield (6352 kg ha-1) and minimum (3940 kg ha-1) in (M3S4) deficit irrigation applied with FYM @12.5 t ha-1 in the year 2018 Sornavari season, respectively. Thus the Tensiometer based irrigation with soil application of humic granules @ 2.5 kg ha-1 can be a feasible approach for increasing grain yield and conserve water in north eastern region of Tamil Nadu, by promoting water use efficiency method in direct rice cultivation areas.

Abstract:
A non-linear model is proposed to describe the growth evolution in mixedwood stands composed of balsam fir (Abies balsamea (L.) Mill.) and red spruce (Picea rubens Sarg.) following a diameter-limit cutting. All softwood stems having a stump diameter equal to or greater than 18 cm were removed during this cutting. The model approach considers the entire stand where the volumes of the two main species, balsam fir and red spruce, were individually modeled. The model was also calibrated for two forest sites identified using Heimburger (1941) forest sites plant index: Cornus and Oxalis-Cornus. On average, the rotation periods suggested by the model range from 25 to 30 years with yields of 4.0 m3ha–1 ear–1 of merchantable volume. In the Cornus forest site, the diameter-limit cutting enables maximization of the yield while maintaining red spruce dominance. In the Oxalis-Cornus forest site, the volume removal has been too important and residual stands were under optimal growth conditions. Furthermore, the cutting has favoured balsam fir instead of red spruce. A reduction of volume removal and an integral protection of red spruce stems having a diameter less than 35 cm at breast height would enable maximization of the yield and maintain the species proportions. Under the Quebec forest context, the selection method would constitute an adequate operation in stand management of forest sites corresponding to Oxalis-Cornus, while cutting with retention of small merchantable stems would be applicable to stands corresponding to the Cornus site.

Abstract:
The results of small-plot field trials of international comparisons of a series of crop management practices for winter wheat grown during 2014–2016 on fertile soils of Central Moravia were assessed. The objective of the experiments was to obtain the highest gross margin (GM), which is the difference between revenues and direct costs. The analyses showed that an optimal level of inputs and costs for obtaining the highest GM could exist. In the assessed series of crop management practices, the optimum input costs corresponded to 11 000–12 000 CZK/ha and 6–9 input measures. At high levels of grains (above 10 t/ha), higher values of GM were obtained by increased efficiency of inputs, but not by increasing their amount to maximize the yields. This indicates the multifunctional and synergic effects of production factors, which can be used at the so-called ecological intensification. Optimizations of inputs can be obtained rather by crop protection than by crop nutrition, which means rather in protection of high yields than in their maximization. Under field conditions, soil and plant processes affected by weather cannot be controlled. Therefore, optimisation of production factors is based both on scientific findings and practical agronomic experience. That is why a universal crop management practice with increased economic and ecological effects cannot be practically proposed.

Abstract:
Farmers in the developed world tend to over-apply fertilizer, and we explore a model for decision-making under uncertainty in yields. This article proposes an agro-economic model for farmer decision-making based on subjective expected yield and crop response to fertilization. The model explores subjective yield probability distributions that are both better suited to subjective crop yields than the previously proposed probability distribution and is easier to extract from farmers. The model allows the analysis of the impact of changes in fertilizer price and variance of expected yields. The model result is consistent with observed farmer behavior based on the rule of “fertilizing for the good years” that appears, according to our model, as rational and consistent with expected profit maximization under yield uncertainty since the cost of over-application is lower than that of the opportunity cost of under-application. The goal of increasing the efficiency of nitrogen use requires both technical innovation and an expansion of the knowledge on the socioeconomic factors underlying excessive crop fertilization that must be improved both to meet future food demands and to prevent environmental degradation and climate change.

Abstract:
We present novel schemes for optimal OFDMA bitrate allocation towards video quality maximization in H.264 scalable video coding (SVC)-based 4G wireless systems. We use the rate and quality models for video characterization of the SVC extension of the H.264/AVC and develop the framework for optimal scalable video transmission. Subsequently, we derive the closed form solution of the optimal H.264 scalable video quantization parameter for sum video quality maximization in unicast and multicast 4G WiMAX adaptive modulation and coding (AMC) scenarios. We also formulate a Vickrey-Clarke-Groves (VCG) auction-based time-frequency (TF) resource pricing scheme for dynamic bitrate allocation and simultaneous prevention of video quality degradation by malicious users for H.264-based scalable video transmission. Simulation results demonstrate that application of the proposed optimal 4G OFDMA schemes for unicast/multicast video quality maximization yield significantly superior performance in comparison to fixed rate video agnostic allocation.

Abstract:
A Field experiment was conducted during the 2018 cropping season, at the Teaching and Research Farm of the Department of Agriculture Federal College of Education, (FCE) Yola. Yola is located in Northern Guinea Savanna Zone at latitude 9o­14’ North and longitude 12o38’ East and altitude of 158m above sea level. The treatments for experiment consist of two potato cultivars (White and Red) which vines were obtained from the open market in Yola and slips prepared from previous year’s tubers. Complete Randomized Block Design (CRBD) was used and the treatments were replicated three (3) times. Both sweet and white potatoes provide similar amounts of key nutrients including protein (2g and 3g respectively), potassium and vitamin B6, all of which contribute to a well-balanced, nutrient-dense diet. It has 20.1g CHO, Starch 20.1g, Sugars 4.2g, Dietary fiber 3g, Protein 1.6g and fat 0.1g. Soups, leaves and shoots are edible, Tubers roasted in many African Countries such as Kenya, South Sudan, Liberia, Guinea and Nigeria.their increased cultivation is being encouraged in Africa where vitamin A deficiency is a serious health problem. he highest yield of 8 tones/ha-1 was recorded on the red cut vines, followed by 6 tones/ha-1 on the white cut vines. There were no significant difference on the spread/uncut vines which gave yields of 3.6 tones/ha-1 and 4.8 tones/ha-1 while significant difference were observed on the cut vines with a mean weight tuber of 6.5 and 8.1 respectively. Results in sweet potato showed that, it has a good potential to the farmers in terms of yield and income. Their increased cultivation is being encouraged in Africa where vitamin A deficiency is a serious health problem. Their differences in terms of yield between the white and the red cultivars might be due to the methods adopted for planting the vines. It is therefore recommended to cut the vines when planting in order to obtain higher yield since yield is an important factor to be considered for sweet potato production.

Abstract:
The worst scenario method is applied to the torsion problem of a homogeneous orthotropic elasto-plastic bar with uncertain yield function. According to the Haar–Kármán principle, the problem leads to a minimization of the complementary energy over a convex set of admissible stresses. The latter set is determined by a yield function with uncertain coefficients. We formulate two maximization problems with respect to the set of admissible coefficients, prove the solvability of the corresponding continuous and approximate problems, and discuss the convergence of some sequences of finite-element approximations.

Abstract:
A field experiment was conducted at the Pulse Research Sub-station of Bangladesh Agricultural Research Institute (BARI), Gazipur during rabi season of 2015-16 and 2016-17 to evaluate the effectiveness of organic and inorganic sources of nutrients in terms of growth and yield maximization of lentil. The experiment was laid out in a randomized complete block design (RCBD) having six treatments with three replications. The treatments were T1= Recommended dose (N20P15K30S10Zn3B1.5 kg ha-1), T2= IPNS (Inorganic) +2.5 t ha-1cowdung, T3= IPNS (Inorganic) +5 t ha-1cowdung, T4= IPNS (Inorganic) +1.5 t ha-1 poultry manure, T5= IPNS (Inorganic)+3 t ha-1 poultry manure and T6= Control. The results reveal that the integrated nutrient management had significant effects on the plant height, number of branches per plant, number of pods per plant, number of seeds per pod, 1000-seed weight, and seed yield of lentil. The maximum seed yield (1216 kg ha-1) as well as protein content (26.1%) were recorded with T4 treatment. The results advocate that satisfying the recommended dose through application of poultry manure @ 1.5 t ha-1 with IPNS inorganic fertlizer could be suggested for achieving yield miximization of lentil in chhiata soil series of Gazipur.

Abstract:
Sustained yield has been a tenet of faith among foresters since forestry emerged as a profession. The concept developed during feudal times when foresters were primarily gamekeepers for landed aristocracy. When the industrial revolution put new demands on forests for fuelwood, foresters extended their "bag limits" to the trees, based on the perception that unregulated markets would result in forest devastation. Early foresters believed that governments must own or regulate forests to perpetuate timber resources. This belief is the basis for extensive public forests today in Canada, the United States and elsewhere. The vision of the early foresters was not reality, but many still cling to their erroneous notions.Markets can and do provide far better information than any sustained yield model about how forests should be managed. Net present value maximization without any sustained yield harvest flow constraints provides a superior way to manage forests and subjects the vision needed to plan for today and tomorrow to meaningful reality checks. Sustained yield constraints greatly distort attempts to measure the effects of alternative management practices for both timber and non-timber outputs.

Abstract:
Experiments were carried out at the research field of Horticulture Research Centre, BARI, Joydebpur during kharif seasons of 2010 and 2011 to find out the requirement of N, P, K, and S application for obtaining higher yield of bitter gourd (var. BARI Karola-1). There were 14 treatment combinations comprising four levels each of N (0, 90, 20,150 kg/ha), P (0, 20, 40, 60 kg/ha), K (0, 40, 80, 120 kg/ha), and S (0, 20, 30, 40 kg/ha). A blanket dose of 2 kg B, 4 kg Zn, and 5 ton cowdung/ha was used. The maximum fruits/plant, fruit size, and single fruit weight and yield of bitter gourd was achieved from the treatment N120 P40 K80 S30 kg/ha and the lowest from the control treatment. The yield benefit for the best treatment over the control was 208% in 2010 and 137% in 2011. Response to N and P was more pronounced in comparison to K and S. The yield increased linearly with increasing rates of N up to 120 kg/ha, P up to 40 kg/ha, K up to 80 kg/ha, and S up to 30 kg/ha and thereafter decreased. The highest gross margin (Tk. 486867/ha) and marginal rate of return (8083%) was also obtained from the same treatment. Overall results reveal that application of N120 P40 K80 S30 kg/ha along with a blanket dose of 2 kg B, 4 kg Zn and 5 ton cowdung/ha appears to be the best treatment for maximizing the yield of bitter gourd in Grey Terrace Soil (AEZ-28) of Joydebpur.
