Abstract:
The present experiment entitled “Development of organic farming package for brinjal (Solanum melongena L.)” was conducted during kharif season of the year 2017 and 2018 at Research Farm of Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar, Maharashtra (India). The experiment was laid out in strip plot design with three replications. The main plot treatments were applied to brinjal comprised of non-chemical weed control modules viz. W1 - Gliricidia leaf mulching @ 5 t ha-1, W2 -Biodegradable mulch (soybean straw) @ 5 t ha-1, W3-Mechanical (hoeing) intercultivation and pulling of weeds, W4- Control -Weedy check, W5- Weed free (Hand weedings with 15 days interval). Different organic nutrients sources and biofertilizers i.e. Azospirillum and PSB as a (1:1) @ 500 g 10 lit-1) as sub plot treatments which comprised of seven organic sources treatments viz., O1- 100% RDN through FYM with biofertilizers, O2-100% RDN through vermicompost with biofertilizers, O3-100% RDN through neem cake with biofertilizers, O4-50% RDN each through FYM and vermicompost with biofertilizers, O5-50% RDN each through FYM and neem cake with biofertilizers, O6- 50% RDN each through vermicompost and neem cake with biofertilizers, O7- 1/3 N each through FYM, vermicompost and neem cake with biofertilizers.
The soil of experimental field was clay loam in texture, low in available nitrogen (181.33 kg ha-1), medium in available phosphorus (15.79 kg ha-1) and high in available potassium (403.56 kg ha-1) with 0.52 per cent organic carbon content. The soil was slightly alkaline in reaction (pH 8.17) with 0.29 dSm-1 electrical conductivity. The soil physical properties viz., bulk density (1.33 g cm-3), field capacity (36.30%) and permanent wilting point (18.32%), hydraulic conductivity (1.71 cm hr-1) porosity (47.33%) indicate that the soil was moisture retentive and suitable for growing brinjal crop in kharif season. The growth parameters viz., plant height, number of primary branches plant-1, number of secondary branches plant-1, total number of branches plant-1, number of leaves plant-1, leaf area plant-1, dry matter plant-1, phenological parameters viz., days to first flower initiation, days to first picking, number of days from first flower initiation to first fruit harvest and physiological parameters viz., Absorbed PAR, photosynthetic rate, CO2 concentration, stomatal conductance, transpiration rate, stomatal resistance, leaf temperature of brinjal were significantly higher under the weed free treatment followed by mechanical (hoeing) intercultivation and pulling of weeds at 20 days interval from 20 to 80 days after transplanting of brinjal crop during both the years of experimentation.
The yield and yield attributes viz., number of fruits plant-1, weight of fruits plant-1, equatorial and polar diameter of fruits, fruit shape index, average weight of fruits, fruit yield significantly higher under weed free treatment followed by mechanical (hoeing) intercultivation and pulling of weeds at 20 days interval from 20 to 80 days after transplanting of brinjal crop during both the years of experimentation and on pooled mean basis.
