SUITABILITY OF CROPS AND CROPPING SYSTEMS FOR CONTINGENCY CROP PLANNING IN RAINFED ALFISOLS OF YSR KADAPA DISTRICT OF ANDHRA PRADESHE. ARUNAAbstract The experiment was conducted at the Agricultural Research Station, Utukur, Kadapa of Acharya N.G. Ranga Agricultural University during kharif and rabi seasons from the year 2017 to 2020. Treatments comprised of three sowing windows viz., August II fortnight, September I fortnight and September II fortnight allocated to main plots and eight different crops and cropping systems viz., Redgram (Asha), castor (DCH 514), cowpea (TPTC 29), horse gram (Local), black gram (TBG 104), foxtail millet (Suryanandi), Red gram + cowpea (1:1) and Red gram + horsegram (1:1) laid out in split plot design with three replications. Green gram (WGG-42) was included from 2019 onwards only. The results indicated that red gram was found as best alternative under contingency with higher net returns followed by castor, cowpea and horse gram in rainfed alfisols of YSR Kadapa district of Andhra Pradesh during normal and excess rainfall conditions whereas horse gram was found as a choice under deficit rainfall conditions. |
