Abstract
A field experiment was conducted during rabi 2021-22 at Holta Organic Farm,
Holta, Department of Organic Agriculture and Natural Farming, CSK Himachal
Pradesh Krishi Vishvavidyalaya, Palampur on evaluation of garden pea varieties
under pea+onion intercropping system and different farming practices. The
experiment consisted of twenty four treatments comprising of four farming practices
(zero budget natural farming, organic farming, inorganic farming and integrated
farming), three garden pea varieties (PB 89, HPM 1 and HPM 2) and two cropping
systems (pure pea crop and pea+onion). The trial was laid out in split split plot design,
replicated thrice, with farming practices in main plot, varieties in sub plot and
cropping systems in sub sub plot. The soil of the experimental site was silty clay loam
in texture, acidic in reaction, medium in available nitrogen, phosphorus and
potassium. Results revealed that integrated farming practices resulted in higher
growth, development and production of pea crop in comparison to other farming
practices and pea variety HPM1 came out to be best performing variety under all the
farming practices. Intercropping with onion resulted in significantly highest increase
in pea equivalent yield under zero budget natural farming (54%). However, highest
pea equivalent yield was recorded under organic farming practices. Quality of both
the crops under study was found to be the best under Organic and Zero budget natural
farming practices. Soil health was significantly improved under organic farming
practices in comparison to others and these also increased the availability of N, P and
K nutrients. Highest net returns were recorded under integrated farming practice
(₹158049/ha), whereas highest B:C ratio was recorded under zero budget natural
farming (2.76).
