Identification of Economically Viable Cropping Systems for Vertisols of Northern Telangana, India: A Recent Study| Chapter 9 | Research Developments in Science and Technology Vol.4

This research was carried out in 2016-17 at the AICRP on Integrated Farming Systems, Regional Sugarcane and Rice Research Station, Rudrur, with the goal of diversifying existing rice-rice cropping systems with less water-demanding crops for vertisols of Northern Telangana Zone under irrigated dry conditions. In a three-replication Randomized Block Design (RBD) experiment, twelve cropping systems were utilised as treatments. During the kharif and rabi seasons, twelve cropping system combinations were examined. On a system level, the turmeric+soybean (1:2) BBF– sesame+blackgram (2:4) turmeric – sesame cropping cycle produced considerably greater production in terms of rice equivalent yield (REY) of 23830 kg ha-1. However, with production of 23332 kg ha-1 and 21389 kg ha-1, it was comparable to turmeric – sesame and turmeric + soybean (1:2) on flat bed – bajra crop sequences. Rice-rice farming strategy had lower production (10725 kg ha-1). Bt. cotton – sesame + black gramme (2:4) on BBF (Rs222838 ha-1) came in first, followed by Bt Cotton + Soybean (1:2) (BBF) – Sesamum + Groundnut (2:4) (Rs221160 ha-1) and Maize+soybean (2:4)–tomato (Rs221160 ha-1) (Rs212909 ha-1). In the traditional rice-rice scheme, lower net returns were recorded (Rs88179 ha-1). Bt Cotton + Soybean (1:2) (BBF)- Sesamum + Groundnut ((2:4) and Maize+soybean (2:4)–tomato were economically better with REE of 152.71 percent, 150.81 percent, and 141.45 percent, respectively. In the vertisols of Northern Telangana Zone, rice-rice farming is less productive and economically inferior for the majority of farmers, indicating a greater possibility to diversify existing rice-rice cropping systems with high-yielding, economically viable cropping systems.
