Abstract
Drought stress uncertain and variable rainfall low soil quality and nutrient deficiencies are among principal constraints for enhancing and sustaining agronomic productivity in rainfed farming in semiarid tropical regions of India Therefore longterm 1985–2004 effects of cropping fertilization manuring groundnut shells GNS farmyard manure FYM and integrated nutrient management practices were assessed on pod yields nutrient status and balances for a groundnut Arachis hypogaea monocropping system The five nutrient management treatments were control no fertilizer 100 recommended dose of fertilizer RDF 204040 N P K 50 RDF + 4 Mg ha−1 GNS 50 RDF + 4 Mg ha−1 FYM and 100 organic 5 Mg ha−1 FYM All treatments were replicated four times The experiment was conducted at Anantapur district Andhra Pradesh on an Alfisol using a Randomized Complete Block design The gap in pod yields between control and different nutrient treatments widened with increase in duration of cultivation Use of diverse fertilizer and manurial treatments produced significantly higher yields than control P 005 Amount and distribution of rainfall during critical growth stages was more important to agronomic yield than total and seasonal rainfall Thus the amount of rainfall received during pegging stage r = 047 P 005 and pod formation stage r = 050 P 005 was significantly correlated with the mean pod yields Whereas use of diverse fertility management practices improved nutrient status in soil profiles N P K S Ca Mg Zn Fe Mn and B after 20 years of cropping yet soil available N K and B remained below the critical limits Longterm cultivation also caused deficiency of S Zn and B which limited the groundnut productivity Crop removal of N P and K during 20 years of cultivation was more in 50 RDF + 4 Mg ha−1 GNS at 523 210 and 598 kg ha−1 respectively With the exception of control there was a positive nutrient balance of NPK in all other treatments Higher positive balance of N and K were observed in 50 RDF + 4 Mg ha−1 GNS 616 and 837 kg ha−1 respectively and those of P in 100 RDF 655 kg ha−1 treatment There was also a net depletion of available S Zn Cu and Mn but a buildup of available Ca Mg and Fe Application of equal amount of GNS was as effective as or even better than FYM in terms of pod yields and nutrient buildup in the soilWe are thankful to Agricultural Production Cess Fund of ICAR Indian Council of Agricultural Research for their financial support and scientific staff of AICRPDA All India Coordinated Research Project on Dryland Agriculture Anantapur centre for technical assistance
