Effect of Different Compost on Performance of Wheat on Integrated Nutrient Management System

Abstract

Wheat (Triticum aestivum L.) is most staple and second most important crop after rice of country, which contributes nearly one third of the total food grain production. It is consumed mostly in the form ofbread as 'chapati'. Wheat straw is used for feeding the cattle. It is being cultivated on an area 28.89 m ha with the production 88.31 mt and productivity of 3057 kg /ha Haryana, Rajasthan and Uttar Pradesh are the leading states in wheat production. In Uttar Pradesh wheat occupy about 9.09 m ha of area with an average productivity of 2696 kg/ha. Non judicious use of chemical fertilizer over a long term in agriculture had shown the adverse effect of soil health and crop yield. Highly productive soils have started showing signs of declining productivity with increasing cropping intensities. Capacity of soil to replenish nutrient level in soil is declining and therefore use of chemical fertilizer increasing day by day. (Balyan and Idnani, 2000). Indiscrimate uses of fertilizer adversely affecting the Physico-chemical properties of the soil resulting in stagnation in productivity. Keeping above facts in view, the present investigation was conducted during 2010- 2011 at Crop Research Centre, Sardar Vallabh Bhai Patel University of Agric.&Tech. Meerut(U.P.) rabi season to work out the best nutrient option in wheat. Field experiments were separately conducted consisting 10 treatment combinations (Control ,100% NPK, 75% NPK + NADEP @ 4 ton/ha-1, 75% NPK + FYM@ 8 ton/ha-1 , 75% NPK + VC @ 2 ton/ha-1 , 100% NPK + NADEP @ 4 ton/ha-1 , 100% NPK + FYM @ 8 ton/ha-1 , 100% NPK + VC@ 2 ton/ha-1 , 125% NPK , 150% NPK.) in randomized block design with three replication. Growth parameters viz. plant height, number of tillers, dry matter accumulations were influenced significantly by different nutrient options. Yield attributes viz. spike length, number of grains/spike, and number of spikelets/spike and 1 000-grain weight were also influenced significantly through by different nutrient options. The significantly higher number of yield attributes and yield was found under the treatment 150%NPK and it was found statistically at par with 125%NPK followed by100%NPK +vermicompost 2 ton/ha-1 In view of monentary gain application of l25%NPK was found best among all the nutrient management options by returning more but on the other hand keeping in view the sustainability of soil health 1 OO%NPK +vermicompost 2 t/ha-1 seems better. Thus 1 OO%NPK + vermicompost 2 t/ha-1 may be suggested for good performance of wheat crop and sustainability of soil health and crop yields in future.
