Study on Selective Mechanization in Kharif Greengram (Vigna radiata L.)

Abstract

Background: Greengram is an important short duration crop for rainfed area of Telangana state. Green gram is grown widely for human diet which contains 25 % protein, 60 % carbohydrate, 1.3 % fat and several essential amino acid including lysine and easily digestable. It is also rich in Vitamin A, B1, B2 C and calcium, phosphorus and potassium. Sowing of seed, application of fertilizers and intercultivation operations should be done timely to get the higher yields and monetary returns besides saving of time and labour, which is possible through only by mechanization in greengram. Methods: This experiment was conducted during Kharif season of 2017 and 2018 at Agricultural Research Station, Madhira farm, Professor Jayashankar Telangana Agricultural University, Hyderabad (Telangana). The soil of the experimental field was clay loam soil in texture, having alkaline reaction (pH=8.3), EC=0.33 ds m-1, low organic carbon (0.18%) and having low available nitrogen (153 kg ha-1), medium in available phosphorus (42 kg ha-1) and high in available potassium (538 kg ha-1). This experiment comprising of two treatments i.e., selective mechanization and normal practice, which was tested by simple t-test at 5% level of significance, non-replicated. Result: Sowing of seed and fertilizer application through seed cum fertilizer drill and intercultivation by tractor drawn implements has shown in good crop growth inturn to get the higher yields and monetary returns besides saving of labour and time in greengram cultivation.
