A field experiment was conducted at Research Farm of ICAR-Directorate of
Groundnut Research, Junagadh for consecutive three summer seasons of
2013, 2014, and 2015 with the objectives of identifying optimum plant
density and nutrient doses under check basin irrigation and drip fertigation
for higher productivity and net returns. The treatments were; three plant
densities viz., 3,33,333 plants/ha (100% of recommended plant density; P1);
4,16,666 plants/ha (125% of recommended plant density; P2), and 4,99,999
plants/ha (150% of recommended plant density;P3) in main plots, and
three nutrient doses viz., 18.75–37.5–22.5 NPK kg ha_1 (75% of recommended
nutrient dose; F1), 25-50-30 NPK kg ha_1 (100% of recommended
nutrient dose; F2), and 31.25–62.5–37.5 NPK kg ha_1 (125% of recommended
nutrient dose; F3) in sub-plots, and replicated thrice. The same
sets of treatments were tested under both check basin irrigation and drip
fertigation. The data were analyzed using split plot design. Pod yield,
haulm yield, and net returns were significantly higher with P3 as compared
to P1 under check basin irrigation but only haulm yield was found significantly
higher with P3 under drip fertigation. Under check basin irrigation,
NH4–N, NO3–N, and available P and K in soil were found in the order
P1>P2>P3 (pF2>F1 (p
