Effect of Planting Systems and Different Nutrient Sources on Physico-chemical Properties of Soil and Performance of Scented Rice (Oryza Sativa L.) in Inceptisol

Abstract

A field experiment was conducted during Kharif season 2017 at Crop Research Centre (Chiraudi) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to evaluate the ―Effect of planting systems and different nutrient sources on physico-chemical properties of soil and performance of scented rice (Oryza sativa L.) in inceptisol‖. The area lie at a latitude of 29o 40‘ North and longitude of 77o 42‘ East with an elevation of 237 meters above mean sea level. The soil of the experimental field was well drained, sandy loam in texture (sand 64.2 %, silt 18.5 %, clay 17.5 %) and slightly alkaline in reaction (pH 8.03). It was low in available nitrogen, zinc and medium in available phosphorus and available potassium with an electrical conductivity 0.25 dSm-1. The experiment consisting three tillage planting systems in main plots (P1-Conventional puddle transplanted rice, P2-Transplanted rice on wide raised bed and P3-Transplanted rice after reduced tillage) and ten nutrient treatments viz. F1- control (no fertilizer), F2 - RDF - 150-60-60 kg N-P-K ha-1, F3 - 75% RDF + FYM, F4- 75% RDF + FYM + Zn, F5 - 75% RDF + FYM + BF, F6 - 75%RDF + FYM + BF + Zn, F7 - RDF + FYM, F8 - RDF + FYM + Zn, F9 - RDF + FYM + BF, F10 - RDF + FYM + BF + Zn in sub-plots was laid out in split plot design with three replications. The data on growth, yield and their contributing traits were calculated on plot area basis (16 m2), whereas content and uptake of nutrients at various stages along with available N, P, K and Zn were recorded as per the standard procedure. Findings revealed that significantly better growth parameter, yield, and was obtained under conventional puddled transplanted rice condition and rice transplanted on wide raised beds. Nitrogen, phosphorus and zinc content and uptake and soil physical properties and having higher water use efficiency and net profit of rice was recorded highest in P2 than rest of the systems. Moreover, potassium content and uptake was found highest under P1. Among fertility levels treatment F10 performed better in relation to growth, yield, nutrient content and uptake than the rest of the fertility levels. Therefore, overall performance was found superior under treatment P2 planting system and F10- RDF+ FYM+ BF+ Zn fertility level during the experimentation in alluvial plain zone of Uttar Pradesh (India).
