EFFECT OF ORGANIC MANURING ON GROWTH, DEVELOPMENT AND YIELD OF HYBRID RICE

Abstract

The dissertation work entitled "Effect of organic manuring on Growth, Development and yield of Hybrid Rice" was undertaken during Kharif cropping season of 2003 at demonstration farm of WRDTC, IIT, and Roorkee. The experiment was conducted in randomized block design with four different treatments of organic manuring namely, Fo, F1, F2 and F3 which represent different quantities of Farm Yard manures applied to paddy field before transplantation of hybrid rice seedlings as mentioned below. FO: = 00 q/ ha Farmyard manure Fl: = 40 q/ha Farmyard manures F2: 80 q/ha Farmyard manures F3: = 120 q/ha Farmyard manures. Each treatment was replicated thrice. So altogether there were 12 treatment plots the objective of the experiment was to determine and study the effect caused by application of different doses of organic manuring on Plant growth, development and yield of Hybrid Rice. The various observations recorded for this study were as follows: 1. .Observation and recording of daily weather data such as minimum and maximum temperature, relative humidity, actual duration of sunshine hours, wind velocity and rainfall. 2. Developments of a program of calculating Et. by modified Penman method on excel software. 3. Calculation of evapotranspiration of a reference crop by modified Penman method. 4. Lysimetric study of daily actual evpotranspiration in hybrid rice grown under organic manuring treatments. 5. Computation of crop coefficient of hybrid rice at different growth stages.
