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.
