Abstract
A field experiment entitled “Effect of moisture regime and integrated nutrients management in hybrid rice (Oryza sativa L.)” was conducted at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during kharif season of 2017-18 and 2018-19. The soil of the experimental field was silt loam, having pH 8.2-8.4, organic carbon (%) 0.30-0.31; available N, P and K values in the tune of 185.00-189, 16.0-16.2 and 282.00-284.00 kg ha-1. The treatments comprised or 4 moisture regime (7cm irrigation 1,4 & 7 DADPW and Conventional irrigation), and 5 integrated nutrients management (100% RDF of NPK through inorganic fertilizers, 75% NPK + 25% N through biocompost, 50% NPK + 50% N through biocompost, 75% NPK + 25% N through FYM, 50% NPK + 50% N through FYM) were tested in split-plot design with three replications. The rice variety Arize-6444 was sown on 8th July, 2017 and 12th July, 2018, with 20 kg seed ha-1 of 150 N:75 P2O5:60 K2O kg ha-1.
The results indicated that application of 7 cm irrigation of 1 DADPW was found significantly superior over 7 cm irrigation at 4 & 7 cm DADPW and conventional irrigation in respect to growth characters, viz., plant height, dry matter accumulation , LAI, number of shoots per running meter, yield and yield attributes. Nutrients management practices had significant effect on growth parameters as well as yield and yield attributing characters. Combined application of 75% NPK + 25% N through Biocompost found significantly superior over rest of integrated nutrients management in respect of growth yield and yield attributing characters. However, application of 75% NPK + 25% N through biocompost gave significantly higher growth, yield and yield attributes of the integrated nutrients management.
