    Effect of sowing dates on different genotypes of radish under organic and natural farming conditions
    (Palampur, 2021-09-14) B R, Sinchana; Chadha, Sanjay
    The present investigation was undertaken to study the effect of dates of sowing on different genotype of radish under organic and natural farming conditions. The trial was laid out in Split-split plot design comprising of three sowing dates (main plot factor) viz., 10th October, 25th October and 11th November, three sub-plot factor (farming conditions) viz., natural farming, organic farming and control and three sub-sub plot factors (varieties) viz., Him Palam Mooli-1, Palam Hriday and Japanese White; with three replications at the ‘Model Organic Farm’ of the Department of Organic Agriculture and Natural Farming, CSKHPKV, Palampur during Rabi 2019-20. The main objectives of the study were to evaluate different genotypes of radish under varied sowing dates and production system, and to study the economics of different treatments. The data were observed on different horticultural and quality traits along with economic indices parameters viz., number of leaves per plant, root length (cm), root diameter (cm), fresh weight of roots (g), shoot length (cm), fresh weight of leaves per plant (g), total fresh weight of plants (g), root-shoot ratio, number of marketable roots per plot, root yield per plot (kg), gross yield per plot (kg), gross yield per hectare (q), total soluble solids (0Brix), dry matter content of leaves (%), dry matter content of roots (%), gross returns, net returns and benefit-cost ratio. Crop sown on 10th October was observed significantly superior in all growth, qualitative, yield parameters and economics followed by 25th October. Among farming condition, Organic farming condition showed superiority over natural farming and control conditions for root length, root diameter, fresh weight of roots, shoot length, total fresh weight of plants, root-shoot ratio, dry matter content of leaves, dry matter content of roots, yield per plot, gross returns and net returns but benefit-cost ratio was maximum in natural farming condition. The cumulative interaction effect among sowing dates, farming conditions and varieties revealed that variety Japanese White sown on 10th October under natural farming conditions (S1F1V3) gave the highest net returns and benefitcost ratio of ₹633983/ha and 9.18, respectively. The second most remunerative treatment combination was S1F1V1 i.e., Him Palam Mooli-1 sown on 10th October under natural farming condition which gave net returns and benefit-cost ratio to the tune of ₹ 593823/ha and 8.60, respectively.
