Validation of Pnutgro Model for Moisture Stress Effects on Rainfed Groundnut in Major Crop Growing Areas of Andhra Pradesh, India - a Critical Review
نویسندگان
چکیده
Groundnut (Arachis hypogaea L.) is an important oilseed crop grown in our country. Majority of crop is under rainfed conditions and as a post rainy season (Rabi) crop in Andhra Pradesh. Several models are available to predict the phenology, growth and yield of groundnut crop. However, no precise models are available to validate the effects of moisture stress on groundnut and their subsequent impacts on yields. This paper reviews critically a PNUTGRO model for predicting moisture stress effects in rainfed groundnut and their ultimate impact on other biometric characteristics of the crop. Detailed account on different aspects relating to the effects of the specified model under study on various aspects of plant growth was studied. Major factors that were under elucidated in the present paper include moisture stress, different dates of sowing, effect of varieties and interaction effect of sowing dates and varieties and crop simulation modelling. The following is a detailed account on Validation of PNUTGRO model under different heads.

Zinc, boron and sulphur deficiencies are holding back the potential of rainfed crops in semi-arid India: Experiences from participatory watershed management
Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...
