Effect of fertility levels and cow urine application as basal and foliar spray on quality and nutrient content of Indian mustard [Brassica juncea (L.) Czernj. & Cosson]

Abstract

Cow urine as a nutrient source along with different fertility levels on mustard is studied at IFS block institute of agricultural science BHU. A split plot field experiment was conducted on mustard (Brassica juncea L. Czern & Coss var. Kalasona) during 2014-15 at the IFS block of Agricultural Research Farm, Department of Agronomy, BHU to examine the effect of fertility levels and cow urine application as basal and foliar spray on nutrient content and quality of Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. The Oil yield (kg ha-1), Seed protein content (%), Protein yield (kg ha-1) and NPK content of seed and stover except P content in seed were observed significantly highest with higher dose of fertilizer dose i.e. 100% recommended dose of fertilizers (RDF), i.e.100:50:50:40, compared to 75% RDF. Among the urine levels basal urine application of 1200 l ha-1 and foliar spray of 50% recorded highest oil and protein yield. N, P, K content of seed and stover were recorded higher with combined application of 100% RDF, basal cow urine level of 1200 l ha-1 and foliar spray of 50% urine.
