Abstract:
The results of 600 on-farm trials with 8 crops conducted during winter season in different districts of Rajasthan have proved that the quantity of urea being applied by the farmers to supply nitrogen to the crops can be successfully reduced to half. The yields obtained with 50% less nitrogen plus 2 sprays of nano-nitrogen in standing crops gave yields higher than that applied in most of the 8 crops tested in these trials. Apart from this, effect of the Nano-Zn and Nano-Cu was also evaluated. As the deficiencies of these micronutrients were not universal like nitrogen, the significant responses

Abstract:
Long-term field experiments conducted under different soil and climate conditions and their databases provide invaluable information and are indispensable means in the study of the productivity and sustainability of the soil management systems. We evaluated the results of the dry matter yields of the main products obtained with four variants of organic and mineral fertilisation in three long-term field experiments established in 1955. The experiments differed in the cultivated crops. The period of evaluation was 12 and 16 years (1985–2000), respectively. The productivity of nine-year

Abstract:
Fertilization is the most expensive cultural practice for the increasing numbers of organic vegetable growers in the United States. Nitrogen (N) is the most important and costly nutrient to manage, and cost-effective N management practices are needed for efficient organic vegetable production. There is a wide array of organic N sources available, but they vary in cost, N content, and N availability. Compost and cover crops are commonly used sources of N for vegetables because they are relatively inexpensive and offer additional nutrients or soil improvement qualities in addition to N. Studies

In recent decades, soil degradation has increased dramatically on a global scale. It is urgently necessary to promote food security and lessen the effects of climate change by restoring and maintaining the health of our soils. Improvements in soil structure have been demonstrated to help mitigate the effects of soil degradation, which is a crucial feature that influences soil health that is becoming more widely acknowledged. So the use of technologies and methods are important in this context. Growing of legume crops in cropping system is an option. Legumes possess a unique attribute known as

Abstract:
An integrated series of field, laboratory and pot experiments was carried out between 1990 and 1993 to study the release of nitrogen from organic manures and its subsequent recovery by crops. The aim was to increase understanding of the soil processes controlling N release from manures and therefore enable N supply to be more closely matched to crop demand in organic cropping systems. The study of N release from manures is handicapped by the lack of appropriate methods to measure rates of mineralisation (both net and gross) in the field.

The crop was planted on 21 October and sampled for plowdown nitrogen content on 1 March.

Planting winter cover crops has several benefits compared to keeping the soil bare. The choice of the cover crop species and sowing date is crucial to have the best cover crops establishment and weed suppression. The seeds germination of cover crops is affected by the sowing date with a preference of early sowing. However, the appropriate date of cover crops sowing is not known. Also, cover crops nitrogen dynamics is variable among species.

This goal has presented a significant challenge to global agronomists and scientists because crops require large inputs of nitrogen (N) fertilizer to maximize yield, but N fertilizers are easily lost to surrounding ecosystems where they contribute to water pollution and greenhouse gas concentrations.
