Effect of foliar nutrition of urea and diammonium phosphate on seed yield and economics of sesame (Sesamum indicum L.) under rainfed situation

Abstract

Field experiments were conducted on deep black soil of Mamurabad farm, Oilseed Research Station, Jalgaon (Maharashtra). Sesame cv. JLT-7 was sown during 2008,2009 and 2010 to find out suitable combination of soil and foliar application of urea and diammonium phosphate for seed yield maximization and remunerative treatments. Result revealed that, soil application of RDF + foliar spray of 2 per cent urea twice at flowering and pod formation stages significantly improved the yield attributes viz., number of capsules plant-1 and number of seeds capsule-1. These attributes contributed in producing significantly higher seed and oil yields and also proved more remunerative over soil application of RDF alone.

Effect of Date of Sowing and Nutrient Management in Summer Sesame (Sesamum indicum L.) under South Gujarat Condition

“…Thus, it could be concluded that the present recommended dose was not enough to meet the nutrient requirement of sesame under existing agro-climatic condition. The results are in close conformity with those of Malik et al, (2003); Reddy et al, (2005); Singhal et al, (2015); Mahajan et al, (2016); Shubha et al, (2017) and Gujjar et al, (2018). Significantly the highest seed yield (791 kg/ha) was recorded when crop fertilized with 100% RDN + 1% Urea (N 4 ) than all other treatments.…”

“…Increase in net return and BCR might be due to higher yields and low cost of cultivation. Similar results were obtained by Singhal et al, (2015); Mahajan et al, (2016) and Akhila et al, (2017).…”

“…The seed and stalk yields were higher with application of 100% RDN + 1% Urea (N 4 ) due to the higher availability of nutrients throughout the crop growth, it led to the increased growth and yield attributes resulting in favourable environment for vegetative as well as reproductive crop growth from initial growth stage to harvest, thus enabling the crop for maximum utilization of nutrients, moisture, light and space, which consequently caused significant increase in photosynthesis and dry matter accumulation, which ultimately led to higher seed and stalk yields of sesame. Similar results were obtained by Nakhlawy and Shaheen (2009); Singhal et al, (2015); Mahajan et al, (2016); Shubha et al, (2017); Vani et al, (2017) and Gujjar et al, (2018). Patel and Raj (2017) and Shamsuzzoha et al, (2019).…”

Influence of Different Sowing Times and Nutrient Management on Growthand Yield of Summer Sesame (Sesamum indicum L.)

“…Higher availability of nutrients throughout the crop growth, it led to the increased growth and yield attributes resulting in favourable environment for vegetative as well as reproductive crop growth from initial growth stage to harvest, thus enabling the crop for maximum utilization of nutrients, moisture, light and space, which ultimately led to higher seed and stalk yields of sesame. Similar results were obtained by Singhal et al [7], Mahajan et al [12], Vani et al [8] and Gujjar et al [9]. Time of sowing and nutrient management failed to exert any significant influence on the harvest index.…”

Effect of Foliar Application of some Zinc and Phosphorus Sources on Controlling Helminthosporium Leaf Spot Disease and Production of Sesame

“…Application of nutrients through foliar spray helps in quick regain in drought situation and also prevents loss of nitrogen in different means. Mahajan et al (2016) revealed that foliar with diammonium phosphate significantly improved the yield attributes, number of capsules per plant and oil%. Krishnaprabu and Kalyanasundaram (2007) revealed that foliar spray of 1.5% diammonium phosphate after 40 and 55 days from sowing increased significantly seed yield of sesame and also recorded the highest seed yield (902 kg/ha) compared to the control (470 kg/ha).…”
