Production of crops is greatly influenced by weather phenomena and therefore any change in climate will have major effects on crop yield and productivity. Using NYD analysis for prediction of crop yield on seasonal basis, it has been observed that maximum temperature may cause the reduction in yield of rice in Eastern Uttar Pradesh by 1.0 to 1.1% per ha by 2020. Similarly, minimum temperature may decrease the yield of rice by 1.5 to 1.9% per ha in Eastern Uttar Pradesh. From future scenario of rainfall it was observed that south-west monsoonal rainfall would be the major factor for contrum temperature may cause the reduction in yield of rice in Eastern Uttar Pradesh by 1.0 to 1.1% per ha by 2020. Similarly, minimum temperature may decrease the yield of ricects that wheat yield may decrease by 5-6% in Bihar state due to increase in maximum temperature by the end of 2080 whereas this decrement in Eastern Uttar Pradesh may be 1.5-2.0%.

The present study was conducted in Ghazipur district (U.P.), India; during 2009-2010 in Kharif maize. Small, medium and larger groups of the farmers has been taken an into account. Improved maize variety resulted higher yield from small to larger ones along with net returns also because all package of practices is being used properly and thoroughly, while from local cheeks the yield and net return was very much poor in all groups. It is therefore to say that avoid local variety. There will be a chance of increasing more and more yield along with net returns if farmers are aware about infestations of weeds and control them thoroughly by using herbicides properly and timely with all other operational actions in time. © 2014, Plant Archives.

The study was conducted during 2009-2010 in Ghazipur district of Uttar Pradesh, Crop was Paddy and Wheat has been taken at different levels of N.P.K. doses concludes that the yield of wheat from zero tillage significantly higher in comparison to conventional tillage practices. This also concludes that the zero tillage techniques are better and fruitful for wheat crop on that field where paddy harvesting was delayed. It was also found that by adopting zero tillage method cost of production was minimized and maximize the production. This techniques also ensure in future if farmers apply all the package of practices properly and timely they will get maximum yield and return. © 2014, Plant Archives. All rights reserved.

An experiment was conducted for increasing the productivity, the genetic variability, heritability and genetic advance was assessed for morphology and quality traits. Wide range of variation was observed for all most all morphological and quantitative traits. In general, phenotypic coefficients of variation were higher than the corresponding genotypic coefficients of variation for all the characters. Early fruit yield-1, plant height, number of fruits plant-1, average fruit weight, pericarp thickness and total fruit yield plant-1 exhibited high estimates of phenotypic (PCV) as well as genotypic coefficient of variation (GCV) indicating substantial scope of improvement in these traits in present material through selection. Estimate of PCV were higher than GCV indicating that apparent variation was not only due to genotypes but also due to environment. High heritability in broad sense (h2b) coupled with high expected genetic advance (GA%) recorded for plant height, number of fruits plant-1, average fruit weight, pericarp thickness, ascorbic acid content, titrable acidity, early yield plant-1 and total yield plant-1, indicated greater scope for further improvement in these traits in advance generations. © 2014, Plant Archives.
