Influence of seeding time, fertility level and genotype on productivity, quality and profitability of garden pea (Pisum sativum)

摘要

The field experiment was conducted during 2017-18 and 2018-19 at Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur, India, to assess the response of pea (Pisum sativum L.) genotypes (‘DPP-SP 6’, ‘DPP-SP 22’ and ‘Pb 89’) tosowing dates (26 October and 10 November) and fertility levels (control, 100 and 125% NPK). The experiment was laid out in factorial randomized block design and each treatment replicated thrice. Early-sown pea (26 October) recorded higher pod yield (10.4 t/ha), being 24% more than late-sown crop along with better pods/plant, average pod weight, harvest duration and economic returns. Higher fertility level at 125% of recommended NPK (62.5:75:75 kg/ha) dose resulted in the maximum pod yield which was about 6% better than 100% NPK (50:60:60 kg/ha) over the years and also showed superior performance for yield attributes and economic returns. Among the genotypes, ‘DPP-SP 6’ significantly superseded ‘DPP-SP 22’ by 15%, and ‘Pb 89’ by 25% for pod yieldand also provided higher net returns (1,43,000/ha) and benefit: cost ratio (2.78). The interactions effects revealed that early sowing of pea genotypes by following either 100% or 125% of recommended dose of NPK (100% NPK; 50-60-60 kg/ha) would be a better preposition for enhancing productivity and profitability under north-western Himalayan conditions.
