Description |
A field experiment entitled “Standardization of seed rate for promising groundnut varieties under rainfed conditions of southern Telangana zone, Andhra Pradesh” was conducted on sandy loam soil at college farm, college of Agriculture, Acharya N.G. Ranga Agricultural University during kharif 2010. The treatments consisted of four groundnut varieties (Narayani, ICGV 91114, K 6 and JCG 88) and four seed rates (75, 100, 125 and 150 kg ha-1). The experiment was laid out in randomized block design with factorial concept and replicated thrice. The results indicated that among the four varieties evaluated, the growth characters viz., plant height, total dry matter production, LAI, CGR and RGR were higher with the varity Narayani followed by K 6 variety which were significantly superior than JCG 88 and ICGV 91114 varieties. Similarly, the yield components like number of pods per plant, shelling percentage, pod yield, haulm yield, harvest index and oil yield were also higher with Narayani and closely followed by K 6 variety which were significantly better over JCG 88 and ICGV 91114 varieties. However oil percentage was higher in JCG 88 variety. As regards to the effect of seed rates, each increment of seed rate (i.e., 75 >100 >125 >150 kg ha-1) significantly increased the growth characters viz., plant height, LAI, dry matter production, CGR and RGR of all groundnut varieties. Similarly pod yield, haulm yield, kernel yield, harvest index and oil yield also increased with increase in seed rate and were more at seed rate of 150 kg ha-1 and were at par with seed rate of 125 kg ha-1. However the yield component i.e. number of pods per plant significantly decreased due to increase in seed rate. Maximum 100 kernel weight (40.83 g) was recorded by ICGV 91114 and followed followed by JCG 88, K6 and Narayani. The 100 kernel weight was at par among 75, 100 and 125 kg ha-1 seed rates and lower value was noticed with a seed rate of 150 kg ha-1. Interaction between varieties and seed rates was found significant and maximum LAI, dry matter production, CGR and pod yield (2150 kg ha-1) was observed with Narayani variety at a seed rate of 150 kg ha- 1 which was at par with same variety at a seed rate of 125 kg ha-1 which in turn was at par with K 6 at a seed rate of 150 kg ha-1. However in JCG 88, they were maximum at a seed rate of 125 kg ha-1 which was at par with same variety at150 kg ha-1 seed rate. Maximum net returns were obtained with Narayani variety at a seed rate of 150 kg ha-1 and then by same variety at the seed rate of 125 kg ha-1. Next to Narayani higher returns were noticed with K 6 variety at a seed rate of 150 followed by 125 kg ha-1 which were on par with each other. B: C ratio also followed similar trend as that of net returns and highest B: C ratio was recorded by Narayani variety at 150 kg ha-1 seed rate and was on par with same variety at seed rate of 125 kg ha-1. Benefit cost ratio of all varieties except JCG 88 was highest at seed rate of 150 kg ha-1 and was at par with seed rate of 125 kg ha-1. Whereas in JCG 88, benefit cost ratio at seed rate of 125 kg ha-1 was higher (1.57) and was at par with that of 150 kg ha-1 seed rate. The results suggest that for obtaining maximum pod yields and economic returns, cultivation of the variety Narayani with a seed rate of 125 kg ha-1 would be advisable under rainfed conditions of Southern Telangana zone, Andhra Pradesh. |
