Description
Conducted a field experiment on "Relative performance of neem (Azadirachta indica) coated urea vis-a-vis ordinary urea applied to rice on the basis of soil test". The field experiment was conducted during Kharif season of 2015 on research plot of Udai Pratap Autonomous College, Varanasi (U.P) adjoining the Department of Agriculture 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 fraction. Treatment of this investigation were consisted of neem (Azadirachta indica) coated urea vis-a vis ordinary urea applied to rice on the basis of soil test. T1 =Control, T2 =Farmer practice, T3=Farmer practice up to R.D of N by ordinary urea, T4=Farmer practice up to R.D of N by Neem coated urea, T5=150% N of R.D by ordinary urea, and T6 = 150% N of R.D by N.C.U Neem coated. The experiment was laid out in a randomized block design (RBD) with three replications in 2015. Soil samples were brought to the laboratory, air dried soil samples were crushed and passed through 2mm sieve.
A despistagem de pragas de insectos nas ervilhas do campo aumentou com o avanço da idade da colheita e os danos reais aos produtos económicos ocorrem após a infestação da broca da vagem. Embora também tenham sido detectadas várias pragas de insectos, parece que quase não tiveram influência significativa no rendimento das culturas.
