MgSO4 application showed significant influence on productivity and quality of safflower. Among the various treatments tested, application of MgSO4 @ 750 ppm at bud initiation (BI) and flower initiation (FI) recorded the higher seed yield (1143 kg/ha). The higher volume weight (728.4g/l) and 100 seed weight (6.04 g) was also observed under the same treatment. The effect of MgSO4 @ 750 ppm at BI and FI was also found significantly superior in terms of SPAD index, RLWC, LAI on A and leaf area. Application of MgSO4 @ 500 ppm was statistically at par with MgSO4 @ 750 ppm at BI and FI in many other parameters under study. Numerically higher net monitory returns (Rs. 17667/ha) and B: C ratio (2.14) was realized with application of MgSO4 @ 750 ppm at BI and FI.
Three fertility gradient stripes were created in Incep-tisols of Odisha by applying no fertilizer, recommended dose of fertilizer (RDF) and double the RDF and paddy was grown during kharif, 2013. These three stripes were subdivided into 24 sub-plots and black gram was grown with different graded doses of fertilizers and manure during rabi, 2013-14. Initial and post-harvest soil nutrient status, nutrient uptake, nutrient requirement, soil efficiency, fertilizer efficiency and yield data were recorded. The highest yield (12.09 q ha-1) was achieved with 30 : 50 : 50 (N : P 2 O 5 : K 2 O). On the basis of these data, fertilizer prescription equations were formulated for targeted yield of black gram in Inceptisols of Odisha.
: A field experiment on 'organic farming' in safflower was conducted at Dry Farming Research Station (DFRS), Solapur for five years (2009-10 to 2013-14) with the objective to explore the possibilities of substituting chemical inputs through organic source and to evaluate its effect on nutrient uptake. Well decomposed farm yard manure, vermicompost, neem seed cake, Azotobacter, Tricoderma and neem seed kernel extract were used as organic inputs. While, urea, SSP, dimethoate and arbendezim were used as synthetic sources of inputs. Significantly higher seed yield (1189 kg ha
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.
