Land suitability evaluation for crops in Warangal district of Telangana under Narsampet division

Abstract

Six typicalPedon's from central and eastern parts of Warangal district, Telangana were evaluated for their suitability to major crops Viz, rice, maize, cotton, chilly and red gram. The suitability classes ranged from highly suitable to permanently not suitable to these crops. Pedon's 1, 2, 3, 4, 5, 6 were highly suitable for cotton, rice, maize, chilly and red gram. Pedon 1,2,3,6 where Pedon's 4, 5 were moderately suitable for chilly, maize red gram and marginally suitable for Pedon 1, 5, 6 for different growing five crops. All the Pedon's were not involved in temporarily not suitable and permanently not suitable any crop. Pedon 1 was also classified as marginally suitable for red gram and moderately suitable for rice, maize, chilly and cotton. Highly suitable for cotton due to alkaline P H and higher ESP. Soils are deep to very deep wetness, O.C. P H and CaCo3 content were limitations in all the Pedon's. Texture was limiting factor.

Soil Type as One of the Major Contributing Factors for Top Ten Agri-Producing States of India

“…The state is situated in such a place that it has a variety of soil. The soils found in Telangana are mostly black soil while it also has red soil, laterite soil, and alluvial soils [81][82][83].…”

“…The black soil of this region is mostly volcanic in origin [81][82][83]. It may also be derived from basalt rock under semi-arid conditions.…”

“…The state of Telangana is covered by igneous depositions such as pink and gray granites and basalt as well as metamorphic depositions like granite gneiss [85][86][87]. Diff erent forms of red and black soils that occur in Telangana region is generally associated with pedogenesis of parent material with diff erent mineralogical composition, conditioned by the drainage and relief [82,83] (Figure 10). seasons are grown that together cover an area of about 53.51 lakh hectares [85][86][87].…”

“…black soils were moderately suitable to highly suitable for cultivation of cotton, sorghum, soybean, green gram, black gram, red gram, sunfl ower, sesamum, maize, and pearl millet while the red laterite soils were considered to be marginally suitable to moderately suitable for cultivation of groundnut, green gram, black gram, red gram, horse gram and pearl millet [82]. Understanding the behavior, nutrient supplying capacities, fertilizer responses, management strategies to be adopted for crop production and potential capability of soils are important to know the quality characteristic features of diff erent soil [83].…”
