Minimum temperature for wheat crop

Estimation of crop water requirement is essential for agricultural planning and irrigation scheduling. The aim of this study was to compute the water requirement of wheat and rice crops for all districts of Haryana. Climatic data on maximum and minimum temperature, rainfall, relative humidity, wind speed and solar radiation were used to estimate the reference evapotranspiration (ETo) at different gridded locations by using Penman Monteith method in MATLAB software.

In the present study attempts have been made to identify a most important weeks for wheat yield at district level. Weekly data of 18 meteorological weeks on (47th to 52nd weeks on first year and 1st to 12th Standard Meteorological Weeks, SMW for 2nd year) on minimum temperature over a span of 20 year (1995 to 2015) has been used along with the annual wheat production data (used as detrened yield for fitting of model) for Faizabad district of eastern U.P. Distribution of temperature has been recorded for wheat crop. Yield of wheat crop was recorded yearly for the study.

This study examines the effect of climatic factor e.g. Maximum Temperature, Minimum Temperature and sunshine variation on the yield of different stages of wheat in during Rabi season 2015-16 at research and instructional farm of IGKV Raipur (CG) India. The correlations of average wheat yield for 14 crop seasons (2001-02 to 2015-16) have been studies for kanchan variety.

A wheat growth model that includes the direct responses of canopy photosynthesis and transpiration to elevated CO2, and the response of crop growth to water stress has been developed and tested. Sensitivity analyses show that different cultivars have quite different responses to changes in ambient air temperature, ambient CO2 concentration and rainfall. Because crops reach maturity earlier under higher temperature, an increase of 3 oC may not impose further water stress to growth of a wheat crop.

Pre harvest crop yield forecast is required for storage, pricing, marketing, import, export etc. Weather is the main factor which affects crop yield. Variability in weather causes the losses in the yield. Use of weather can be done for crop production forecast. Weather plays an important role in crop growth. Therefore model based on weather parameters can be provide reliable forecast in advance for crop yield. In this study, the focus was on the development crop yield forecast (CYF) model through stepwise linear regression technique using weather variables and historic crop yield.

The present investigation was carried out with 32 diverse genotypes of bread wheat in completely randomized block design with 3 replications at Norman E. Borlaug Crop Research Centre, G.B. Pant University of agriculture & Technology Pantnagar for screening the genetic diversity for yield and physiological traits under normal sown condition. The observations were recorded on 16 agronomic traits and 3 physiological traits. The statistical analysis for genetic divergence was done using Mahalanobis-D 2 statistics and clustering of genotypes was done using Tocher method.
