Abstract Fruit number and weight per tree were recorded for 3 years for 2 avocado (Persea americana M.) cultivars—‘Booth 8’ and ‘Peterson’. Sample variances were used to determine the number of years per experiment and trees per treatment required to detect differences in yield among treatments at the 5% and 10% significance levels for each cultivar. Yearly variability was greater than variability among trees for both cultivars. Yearly variability for total fruit weight was greater for ‘Booth 8’ than for ‘Peterson’. Fifteen trees per treatment were required to detect a 10–20% difference in tot

Despite this, the performance of rice crops with straw applications has received little attention.

Straw return plays a vital role in crop yield and sustainable agriculture. Extensive research has focused on the potential to enhance soil fertility and crop yield through straw return. However, the potential impacts of straw return on saline–sodic soils have been relatively neglected due to the unfavorable characteristics of saline–sodic soils, such as high salinity, poor structure, and low nutrient contents, which are not conducive to crop growth. Therefore, a two-year field experiment was conducted to assess the effects of straw management (retention or removal) with nitrogen fertilizers (0

Abstract. Monitoring staple crop production can support agricultural research, business such as crop insurance, and government policy. Obtaining accurate estimates through field work is very expensive, and estimating it through remote sensing is promising. We estimated county-level maize yield for the 37 maize producing countries in Kenya from 2010 to 2017 using Moderate Resolution Imaging Spectroradiometer (MODIS) data. Support Vector Regression (SVR) and Random Forest (RF) were used to fit models with observed county level maize yield as a function of vegetation indices. The following five M

In order to evaluate the effect of barley/chickpea intercrop, a study was carried out in the research field of Faculty of Agriculture, Maragheh University, in 2009 as randomized compelet block design, with three replicates, with row replacement series. Treatments included different combinations (1:1,2:1, 3:1, 2:2 and 3:2 row ratios of barley:chickpea) and their monocultures.
