Ten rice genotypes were evaluated to study the genetic variability, correlation and path analysis under aerobic conditions for selection of high yielding genotypes. The experiment is carried out in RCBD with 3 replications and the data is analysed in SPAR 2.0, Past 4.01 and OPSTAT for variability, correlation and path analysis respectively. The phenotypic and genotypic coefficients of variation were high for the number of productive tillers per plant, the number of filled grains per panicle, 1000-grain weight, biological yield and grain yield indicating the possibility of genetic improvement through direct selection for these traits. The magnitude of difference between PCV and GCV was less for the traits indicating little influence of environment. High heritability coupled with high genetic advance was recorded for the number of productive tillers per plant, the number of filled grains per panicle, 1000-grain weight, spikelet fertility, biological yield and grain yield indicating a preponderance of additive gene action, which provide excellent scope for further improvement by selection. Significant positive association of grain yield with number of productive tillers per plant, panicle length, number of filled grains per panicle, 1000-grain weight, spikelet fertility and biological yield was observed. Path analysis revealed the traits, number of filled grains per panicle exerted highest positive direct effect on grain yield followed by 1000-gain weight and number of productive tillers per plant. Thus, these traits which contribute to the grain yield under aerobic condition could be exploited for further breeding programme.

SUMMARY :A field experiment was conducted to evaluate new rice culture RDR 1140 for different methods of establishments during Kharif 2016 -17 at Regional Sugarcane and Rice Research station, Rudrur, Nizamabad (district). It was laid out in split plot design viz., new rice culture RDR 1140 and popular existing variety MTU 1010 as main plots and three planting methods -Broadcasting sprouted seed on puddled seedbed, Drum seeder planting (Wet) and Normal transplanting. No significant difference in grain yield was noticed for two varieties but planting methods significantly influenced grain yield. Normal transplanting method and Direct sowing with Drum seeder method recorded at par grain yield of 8426 kg ha -1 and 8195 kg ha -1 , respectively and it was significantly higher over Broad casting method with grain yield of 5120 kg ha -1 . Among two rice varieties RDR 1140 recorded yield advantage of 5.8% with two days early maturity in Drum seeder and 19% yield increase with three day early maturity in Normal method over existing popular variety MTU 1010.Hence RDR 110 can be recommended over existing variety MTU 1010 either through Normal transplanting method or Direct seeding with Drumseeder depending upon available resources with farmer.How to cite this article : Shahana, Firdoz, Kishore, N.

Sugarcane variety 85R186 was intercropped with six different winter crops to identify most profitable intercrop. The experiment was conducted in randomized block design with three replications.The treatments comprised T1-sole sugarcane, T2 -SC + Coriander (leaf), T3-SC + Methi, T4 -SC + Cabbage, T5 -SC + Cauliflower, T6-SC + beetroot and T7 -Sugarcane + Wheat. Higher equivalent cane yield was recorded in Sugarcane + cauliflower (126.88) and Sugarcane +beetroot (126.26) & Sugarcane + cabbage (123.66) intercropping combination. Intercropping increased net returns significantly with Sugarcane + beetroot (Rs 2,60,695.00 ha-1), Sugarcane + cabbage (Rs 2,37,540.00 ha 1) &Sugarcane + cauliflower (Rs 2,29,820.00 ha-1) over sole sugarcane (Rs 144355.00 ha 1). Higher Monetary advantage index (MAI) value was obtained from sugarcane + beetroot (138171) & sugarcane + cabbage (136565) intercropping system.
