Abstract:
A field experiment was conducted during Zaid season 2021 at Shuats Model of Organic Farming (SMOF), Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P), India to determine the “effect of plant geometry and Organic manures on growth and yield of Baby corn (Zea mays L.). The experiment consists of two factors Plant geometry and Organic manure, there were 9 treatments each being replicated thrice viz. T1 (35 cm x 20 cm + Farm yard manure), T2((35 cm x 20 cm + Poultry manure), T3(35 cm x 20 cm + Vermicompost), T4 (45 cm x 20 cm + Farm yard manure), T5(45 cm x 20 cm + Poultry manure), T6(45 cm x 20 cm + Vermicompost), T7 (55 cm x 20 cm + Farm yard manure), T8(55 cm x 20 cm + Poultry manure) and T9 (55 cm x 20 cm + Vermicompost) and laid out in Randomized Block Design. The results revealed that there was increase in the growth parameters of baby corn viz., plant height (106.23 cm), dry weight (46.53 g), Crop growth rate (108.76 g/ m2 /day), Relative crop rate (0.053 g/day) with the application of the treatment T9 (55 cm x 20 cm + Vermicompost). Application of treatment T9 (55 cm x 20 cm + Vermicompost) recorded maximum in No of cobs per plant (3.16), cob length (8.40 cm), cob weight with husk (44.80 g), cob weight without husk (13.18 g) and cob yield (5.59 t/ha), Cost of cultivation (46049 INR/ha), Gross returns (163800 INR/ha), net returns (117751 INR/ha) and B:C ratio (2.55). On the basis of this experiment it is concluded T9 (55 cm x 20 cm + Vermicompost) was found to be more productive.
