Nutrient management in short duration pigeon pea [Cajanus cajan (L.) Millsp.] in the southern laterites of Kerala
Keywords:
growth, nutrient management, pigeon pea, protein, solubilisers, seed yieldAbstract
The field experiment to standardise the nutrient management practice in pigeon pea (APK1) was conductedin randomised block design with eight treatments comprising of different nutrient sources and methods ofapplication, at College of Agriculture, Vellayani, Thiruvananthapuram. Significant variations were recordedin growth parameters, yield attributes, yield, nitrogen uptake and protein content of seeds. The treatmentinvolving application of 100 % N + 50 % P + 50 % K + P solubiliser + K solubiliser in soil resulted in thesignificantly tallest plants (109.70 cm) and maximum number of branches per plant (6.5) at harvest, averagepod weight (0.62 g) and seed yield (1.48 t ha-1). Seed protein content was also maximum in the treatment,indicating that the integrated package of 100 per cent recommended dose of nitrogen and substitution of 50per cent each of phosphorus and potassium with P solubiliser (Bacillus megaterium) and K solubiliser(Bacillus sporothermodurans) can be recommended for pigeon pea cultivation in the southern laterites ofKerala.References
