Sustainability of Pod Yields of Groundnut through Crop Seasonal Rainfall, Length of Growing Period and Cultivated Area under Arid Alfisols of Anantapur in South India

A study was conducted with the objective of assessing effect crop seasonal rainfall and length growing period on sustainability pod yields groundnut attained in 31 mandals under arid Alfisols Anantapur Andhra Pradesh. We have considered variability regard to (i) (mm) (ii) yield (kg/ha) during 2001 2020; (iii) extent area (ha) 2009 (iv) (days). Based mean standard deviation (SD) each parameter, were classified into 5 groups viz., G1: Less than (Mean–2SD); G2: (Mean–2SD) (Mean–SD); G3: (Mean–SD) (Mean+SD); G4: (Mean+SD) (Mean+2SD); (v) G5: More (Mean+2SD). Out mandals, 22 for rainfall, 20 LGP 18 fallen G3. Estimates correlation derived between area, mandal over years tested significance assess superiority mandals. Significant observed which ranged from 0.433 at Kalyandurg 0.765 Putlur. Similarly, significant (-0.764), Brahmasamudram (-0.674) Rapthadu (-0.584) The predictability prediction error based a regression model calibrated through different gave (R2 ) value 0.46 90.9 kg/ha indicated negative positive yield. index 26.6% (Kambadur) 87.5% (Peddavadagur) 53.9% (CV 30.1%) years. Ranks assigned variation yield, SYI rank sums derived. Guntakal, Gooty Vidapanakal superior 30, 38 70 respectively. Guntakal an 16570 ha 17.3%), 436.1 mm 33.4%), 140 days, 644 70.9%) 76.5%, while 14146 14.6%), 429.6 42.4%), 663 69.1%) 79.1%. 5077 31.1%), 403.2 47.4%), 654 49.5%) 77.9%. Due maximum we recommend that farmers these could enhance attain sustainable Alfisols.
