Water is the primary input for crop production and increasingly becomes scarce due to its high demand in agricultural sector. Quality of water is assuming great importance with the increasing demand in industries, agriculture and rise in standard of living. Agriculture is the major user (89%) of India’s water resources. However, dwindling of freshwater resources and deterioration of irrigation water quality due to its overuse to meet up the high demands in agriculture sector becomes the serious concern in sustainable crop production. Clay pot irrigation in its simplest form consists of unglazed baked clay pots, which are buried up to the neck in the soil and filled with water. This method is one of the most efficient systems of irrigation known and is ideal for many small farmers. Clay pot irrigation, a traditional system of irrigation alternative to drip method is the latest advancement and effective innovation of localized methods of irrigation and found suitable where water scarcity becomes major stress for crop production. It also helps to improve soil physical properties particularly the structural status in soil and also enhances the water use efficiency of the crop, soil organic carbon and builds up soil fertility.
A field experiment was conducted to study the effect of nitrogen and phosphorous on growth and yield of finger millet (Eleusine coracana (L.) at Centurion University, Paralakhemundi during summer (February-May), 2018. The combination of four nitrogen levels (0, 30, 60 and 90 kg ha-1) and three levels of phosphorus (0, 20 and 40 kg ha-1) were tested in Split plot design with three replications. There was a significant improvement in plant height and yield attributes with the application of 90 kg N ha-1 as compared to lower levels of N application. With increase in levels of Phosphorus from 20 and 40 kg ha-1 has significantly increased yield. Significantly higher grain (1054kg ha-1) and straw yield (4369kg ha-1) were recorded with the application of 90kg N ha-1 and 40 kg P2O5 ha-1 while, the minimum yield was observed with 0 kg N ha-1 and 0 kg P2O5 ha-1.
In [Pal \textit{et al.}, arXiv:2206.03552], the authors discuss how an unsupported flat annulus contracted at its inner boundary by fraction $\Delta$, buckles into a radial wrinkling pattern that is asymptotically...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
