EFFECT OF BIO-FORMULATIONS ON GROWTH AND YIELD OF PEA(PISUM SATIVUM L.)Michi Yarang, Chowlani Manpoong, Avinash Sharma, Megha Raghavan and V.S. DevadasAbstract An experiment was conducted to study the effect of different bio-formulations on performance of gardenpea (variety-Sakata, Sweet Pearl) under Namsai conditions of Arunachal Pradesh in the Agricultural ResearchFarm of Arunachal University of Studies. The experiment consisted of 10 treatment combinations involvingthree doses each of Bio-N (4, 5, 6 t/ha), Bio-P (2, 3, 4 t/ha) and Bio-K (2, 3, 4 t/ha) with uniform dose of pHregulator and organic manure in three replications in a randomized block design. Application of Bio-N:Bio-P:Bio-K @ 4:3:3 t/ha recorded the maximum plant height and maximum number of branches per plant.Number of pods and weight of pods per 100g was found highest in T2 (Bio-N 4t/ha + Bio-P 3t/ha + Bio-K3t/ha) and maximum length of pods in T1 (Bio-N 4t/ha + Bio-P 2t/ha + Bio-K 2t/ha) which was at par withT2. The maximum yield (6.63 t/ha) was obtained in T2 (Bio-N 4t/ha + Bio-P 3t/ha + Bio-K 3t/ha), T4 (Bio-N 5t/ha + Bio-P 2t/ha + Bio-K 2t/ha) and T6 (Bio-N 5t/ha + Bio-P 4t/ha + Bio-K 4t/ha) respectively. Thehigher quantity of Bio-P and Bio-K in T2 showed a significant contribution in increasing the yield of crop.Considering the overall performance and comparative doses the application of Bio-N:Bio-P:Bio-K @ 4:3:3t/ha can be recommended for eastern himalayan agro-climatic conditions. |
