Abstract
A field in vestigation on “Effect of shadenet colours and foliar spray of boron on growth and yield of summer okra” was carried out at Post Graduate Institute Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri (M.S.) with a view to study the effect of shadenet colours and foliar spray of boron on growth and yield of summer Okra, 2013. The soil of the experimental field was red sandy clay in texture with low in available nitrogen (159.78 kg ha-1), moderate in available phosphorus (18.65 kg ha-1) and high in available potassium (433.60 kg ha-1) and sufficient micro nutrients viz., copper (1.66 mg kg-1), manganese (2.56 mg kg-1), iron (4.82 mg kg -1) and deficient in boron (0.50 mg kg-1). The field capacity, permanent wilting point and bulk density was 25.72 per cent, 13.01 per cent and 1.42 g cm-3 respectively. The experiment was laid out in factorial randomized block design with three replications. The treatments consisted of six coloured shadenets viz., white, blue, green + white, green, red and black along with open field condition and one variety viz.,With Boran and without Boron foliar spray. The Red shadenet colour (35 % shading intensity) found more suitable to obtain significantly maximum growth, yield attributes and fruit yield of green Okra (27.8 t ha-1) followed by green colour ( 26.5 t ha-1).The open field condition recorded significantly minimum growth, yield attributes and fruit yield of green Okra( 15.5 t ha-1) as compared to different shadenet colours. The physiological parameter viz., photosynthetic rate, absorbed photo synthetically active radiation, CO2 concentration, stomatal conductance and transpiration rate were siginificantly higher under Red shadenet colour while stomatal resistance and leaf temperature showed reverse trend. The number of days required to flower initiation was not influenced significantly due to different shadenet colours. The chlorophyll content in okra was found significantly higher under red shadenet than rest of shadenet colours and open field condition. Maximum and significantly higher gross monetary returns (Rs. 33626 unit-1 of shadenet) and net monetary returns (Rs.21621 unit-1 of shadenet) obtained with Red shadenet colour. The variety with Boron foliar spray was found significantly superior in respect of growth, yield attributes and fruit yield of okra (28.67 t ha-1).
