Research on the effects of ultraviolet-B (UV-B) radiation on soybean seed quality is limited. The objective of this study was to quantify UV-B doses, 0, 5, 10 & 15 kJ•m −2 •d −1 , on soybean growth and seed quality. The experiment was conducted in the Soil-Plant-Atmosphere-Research (SPAR) facility. Chambers located at the R.R.
This study characterizes soil physico-chemical properties of a toposequence located in the Patana block ofKeonjhar district of Odisha. Three different representative pedons situated at three different topographicpositions viz. foothill land, medium land, and stream terrace land were exposed for evaluating horizonwise soil physico-chemical characteristics. Results indicated that soil pH, clay, porosity, water holdingcapacity, soil organic carbon (SOC), exchangeable bases, and cation exchange capacitygradually increasedfrom higher to lower topographies, whereas a reverse trend was observed for bulk and particle densities.Significant positive correlations have been observed for soil porosity, water holding capacity, exchangeablebases, and cation exchange capacity with clay; base saturation and exchangeable bases with pH.In contrast,significant negative correlations of bulk density and particle density with SOC;pH and exchangeable baseswith exchangeable acidity were also observed.
Integrated use of .organic and inorganic fertilizers can improve crop productivity and sustain soil health and fertility. The present experiment was conducted during rainy season of 2011, 2012 and 2013 at groundnut Research Farm, Orissa University of Agriculture and Technology, Odisha to study the effect of nutrient management practices on maximizing the production of groundnut crop. The results revealed that different nutrient management practices exerted significant influence on pod yield and yield attributes of groundnut under rain fed conditions. Application of FYM @ 7.5 t/ha plus recommended dose of NPK/ha (20 kg N, 40 kg P 2 O 5 and 40 kg K 2 O/ha) along with soil application of critical micronutrients (10 kg borax/ha) produced higher pod yield (1457 kg/ha) and higher net monetary returns (Rs.7096 /ha) as compared to application of recommended dose of NPK/ha with or without FYM @ 7.5 t/ha (1332kg/ha, Rs. 5305 /ha and 1105 kg/ha, Rs. 2710 /ha, respectively). The same treatment recorded significantly highest number of root nodules per plant at 40 DAS(15.6) and 80 DAS (18.9) and maximum number of pods/plant (18.6) 100 kernel weight (33.0) and shelling per cent (64.2) as compared to other fertility levels. Foliar application of urea also significantly influenced pod yield of groundnut. However, foliar application of urea @ 2 per cent at 30 and 60 DAS exhibited maximizing pod yield of 1350 kg/ha which is 11.6 per cent higher than no foliar application (1210kg/ha). It was concluded that to get maximum productivity and profitability from groundnut during rainy season in acidic soils of Odisha, the crop should be managed with 7.5 t FYM/ha + 100 per cent recommended dose of fertilizer as basal + foliar spray of 2 per cent urea at 30 and 60 DAS.
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.
