RESUMEN

A field experiment was conducted during rabi, 2019-20 and 2020-21 at the PG experimental plot of the Department of Agronomy, BNCA to assess seed priming and moisture conservation measures on productivity and profitability of baby corn under the rainfed situation. The soil of the experimental site was acidic (pH 4.64), sandy loam in texture, medium in organic carbon (0.64%), low in available N (232.06 kg ha-1), P2O5 (13.84 kg ha-1) and K2O (115.27 kg ha-1). The experiment was laid out in factorial randomized block design with 4 levels of seed priming methods. S0: No priming; S1: Seed priming with 1% urea solution; S2: priming with 1% potash solution (MOP); S3: priming with 3 times diluted cow urine and 3 levels of soil moisture conservation measures viz. M0: No mulching; M1: use of bio mulch; M2: use of black polythene mulch. Results revealed that the highest and quickest seedling emergence (11.96 numbers m-2) was recorded under the treatment of seed priming with three times diluted cow urine which was at par with the treatment of seed priming with 1% urea and 1% KCl (MOP) solution. The total number of leaves m-2, total leaf area plant-1 and leaf area index (LAI) of baby corn were also changed significantly due to different moisture conservation measures but those parameters remain static due to different seed priming methods. The CGR (g m-2 day-1), RGR, (g g-1 day-1) and NAR (mg cm-1 day-1) of baby corn were also changed significantly due to different soil moisture conservation measures. The highest and most significant baby corn yield without husk(22.59 q ha-1) with 305.61 q ha-1 of green fodder yield along with harvest index (6.00), production efficiency (25.67 kg?1 day-1 ha-1) and nutrient use productivity (9.41 kg?1 ha-1 kg-1) were recorded under the treatment where black polythene mulching was used as soil moisture conservation measure.

RESUMEN

The greater challenges of the 21st century is affordably meeting nutritious food demand for a world population which were expected to surpass 9.6 billion people at middle of the century and at the same time sustaining a quality and quantity of a natural resources and biodiversity. Coming to the reality a need of urgent attention for technological innovations in a sector of food production ultimately leading for “greater protein and energy production per unit of resource input”. Therefore, a field experimented was conducted at Chamelti Agriculture Farm, MS Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, Solan during kharif season of 2022 to study the effect of row spacing and nitrogen sources on growth, yield and economics of babycorn. The results reveals that significantly higher growth and yield attributing characters were observed with wider spacing of (R3) 60 cm and (N4) nano urea. However, higher yield and economic returns were significantly higher with row spacing of (R2) 45 cm along with (N4) nano urea. On the basis of B: C ratio, row spacing of (R2) 45 cm along with (N4) nano urea was found to be remunerative for baby corn under Mid hills of Himachal Pradesh.
