Description Abstract

A field experiment was conducted in Kharif season of 2014 at, J.N.K.V.V. College of Agriculture, Instructional Farm, Rewa (M.P.) under All India Coordinated Rice Improvement Project to study the effect of sowing dates on performance of different rice varieties under upland condition. Objective of this experiment was to find out the effect of sowing dates on growth and yield parameters of different rice varieties, suitable rice varieties under upland condition and economics of different treatment.
The experimental field was sandy clay-loam in texture. It was just below neutral in reaction (pH 6.5) with normal electrical conductivity (0.42 dS/m). The organic carbon content was low (0.56-0.60%) while medium in available N,P and K contents 294-337, 18-36 and 314-611 kg/ha, respectively).
The experiment was laid out in split-plot design with four replications. The treatments comprised of three sowing dates (3rd July, 8th July and 13th July) in main plots and 5 varieties (Danteshwari, Vandana, IR-64, PS-3 and PS-5) in sub plots. The varieties were sown by direct-seeding on 3rd, 8th and 13th July.
The uniform dose of fertilizers (100 kg N, 60 kg P2O5 and 40 kg K2O/ha) were applied in all the treatments. The crops were grown under recommended package of practices. Various observations were recorded periodically in relation to growth and yield attributing characters and finally, economics of the treatments was calculated.
Among the varieties, PS-3 and then PS-5 resulted in maximum growth parameters , yield attributes and grain yield up to 40.90 to 43.27 q/ha with net income up to Rs. 48652 to 49778/ha. The most optimum date of sowing of upland rice was 3rd July which gave maximum growth parameters, yield attributes and grain yield unto 38.54 q/ha with net income up to Rs. 41446/ha. Thus, variety PS-3 or PS-5 grown on 3rd July was suitable to obtain maximum productivity and economical grain from rice under upland conditions of this region.
