Effect of Intercropping Greengram and Blackgram in Sesame for Augmenting the Productivity and Rain Water Use Efficiency Under Rainfed Upland Condition

Abstract

1),T 10-Sesame + Blackgram (2:2), T 11-Sesame + Blackgram (3:1).) in a Randomized Block Design with three replications. Considering the sesame as base crop, sesame, greengram and blackgram were sown simultaneously as per treatment during post kharif seasons (Mid August-Mid September). It was observed that intercropping of sesame in green gram and blackgram had significantly superior value in respect of the Sesame Equivalent Yield (SEY), Land Equivalent Ratio (LER), Rain Water Use Efficiency (RWUE) net return and B : C ratio. From the pooled data of three years, the highest SEY (13.85q/ha) was recorded by T 8-Sesame + blackgram (1:1) followed by Sesame + Greengram (2:2) and Sesame + blackgram (2:1). The highest LER (1.42), RWUE (7.42kg/ha/mm), Net return (` 39,374/ha) and B: C ratio(4.40) was also recorded in Sesame + Blackgram (1:1).

Performance of Sesame (Sesamum indicum L.) based Intercropping System in kharif under Different Row Proportion on Yield and Economics

“…Among all the intercropping tested, sesame : black gram in 1:1 row ratio gave maximum B:C ratio followed by sesame : black gram in 2:1 row ratio which might be attributed to higher gross monetary return compared to the cost involve in production. Similar result is also reported by Sarma et al [8].…”

“…) followed by 2:1 and 3:1 row ratio this might be due to higher plant population and higher number of pods plant -1 in this treatment. Similar results were also reported by Bindhu et al [7] and Sarma et al [8].…”

“…) than other intercropping treatments. Bindhu et al [7] and Sarma et al [8] also recorded more seed yield in sole crop of sesame and Sesame: Black gram in 3:1 row ratio. Cultivation of sesame + green gram (1:1) gave 36.80% higher net return as sole sesame cropping [9].…”

Crop Diversification for Enhanced Productivity in the Southern Laterites of Kerala

“…The higher seed yield of black gram might be due to the higher test weight of black gram compared to green gram. Similar observations have been made by Sarma et al (2016) in studies conducted with intercropping black gram and green gram in sesame.…”

Effect of Different Planting Geometry and Sulphur Fertilization on Growth and Yield of Sunflower in Sunflower + Greengram Intercropping System

“…However, the test weight is not influenced significantly due to plant geometry levels.The improvement of growth attributes leads to higher yield attributes and also absence of competition from intercrop resulting in higher nutrient uptake, higher photosynthetic assimilates production and effective portioning from source to sink (Saleem et al, 2008). The results were in agreement with the findings of Sarma et al, (2016).…”
