ABSTRACT
A field experiment was conducted on gingelly during summer season of 2022 in sandy loam soil at farmer’s holding at Vallampadugai village, Cuddalore district, Tamil Nadu, India to study the effect of combined application of inorganic fertilizers, organic manure, biofertilizer and seaweed extract on growth, yield attributes and yield of gingelly. The experiment was laid out in randomized block design and replicated three times. The growth, yield attributes and yield were recorded at 30 DAS, 60 DAS and at harvest stage. The results of the experiment revealed that the application of 75% recommended dose of fertilizers + poultry manure @ 10 t ha-1 + seaweed extract @15% registered the maximum growth attributes viz., plant height, number of branches plant-1, number of leaves plant-1, leaf area index and chlorophyll content. The highest value of yield attributes viz., number of capsules plant-1 (89.36), number of seeds capsule-1 (75.79), 1000 seed weight (3.36 g) and seed yield (1064.2 kg ha-1), stover yield (1874.3 kg ha-1), biological yield (2938.5 kg ha-1) and harvest index (36.22 %).
