Effect of Major Nutrients and Vermicompost on Crop Productivity of Mustard (B. juncea L.) Crop

Abstract

The present investigation involved field experimentation conducted during Rabi season of year 2015-16 followed by laboratory analysis of the plant and soil sample. All grass have been removed from the plot and on crop productivity of mustard (B. juncea L.) plots and soil samples have been taken from each plot at 30 DAS, 60 DAS and at harvesting. Khurpi and auger have been used as sampling tools. Sample were collected in plastic bag. The experiment was conduct on research plot of Udai Pratap Autonomous College, Varanasi (U.P.) adjoining the department of Agricultural Chemistry and Soil Science. The soils of Varanasi formed on alluvial, deposited by river Ganga have predominance of Illite, quartz, feldspars and Illite minerals are partly inherited from micas which are predominant in the sand and silt fractions. Varanasi is found under sub-tropical climate and situated in eastern U.P, India. The precipitation in this region is normally spread over period of three and four months. i.e form the last week of June to the second week of October is rain season. The distribution of average annual rain fall is 96.65mm of which 80% from June to September, 5.7% from October to December, 3.3% from January to February and 3.0% from march to May. Treatments of this investigation consisted of integration of N,P,K,S and vermicompost are T1 Control, T2 50% NPKS, T3 50% NPKS+10t, Vermicompost/ha, T4 100% NPKS, T5 100% NPKS+10t Vermicompost/ha T6, 150% NPKS & T7 200% NPKS. Result pertaining the effect of various treatment of different level of NPKS on different growth stages of mustard crop. The effect of different doses of NPKS+ vermicompost different growth stages of mustard crop was found in the order T5>T7>T6>T3>T4>T2>T1 and values were 90 DAS, 131.33,129.00,127.67,118.33,124.65,111.00 under the respective treatment. Similarly higher plant height was recorded with T5 treatment as compared to other treatment at all growth stages. Plant height increased with increasing the levels of NPKS. Similarly higher plant height was recorded with the application of 100% NPKS+10t vermicompost/ha. The grain yield of mustard crop as influenced by various treatment could be arranged in order to T5>T7>T6>T3>T4>T2>T1 and value were18.12, 17.35, 15.00, 10.20, 12.10, 8 and 6q/ha under the respective treatment.
