Influence of plant spacing and fertility levels on growth, yield and economics of long duration pigeonpea (Cajanus cajan L. Millsp)

Author(s): Akhilesh Mishra and Karam Husain
Abstract: The field experiment entitled “Influence of Plant spacing and Fertility Levels on Growth, Yield and Economics of Long Duration Pigeonpea (Cajanus cajan L. Millsp)” was conducted at OilSeed Research farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experimental field was levelled and well drained. The soil was clay loam in texture, low in organic carbon and available nitrogen, medium in available phosphorus, high in available potassium and moderately alkaline in reaction. The environmental conditions prevailed during experimental period was favorable for normal growth and maturity of pigeonpea crop. The experiment was laid out in Factorial RBD with four spacing and three levels of fertilizer which comprises twelve treatment combinations. Each experimental unit was replicated three times. Experiment was conducted continuously two years in kharif2016 and 2017 with four spacing (60x30cm2, 60x45 cm2, 75x30cm2 and 75x45cm2) and three fertility levels (RDF 75%, RDF 100% and RDF 125%) as per treatments. Crop variety “AMAR” was sown on ridges. Significant plant height, 100 grain weight, seed yield, stalk yield, net return and benefit cost ratio were recorded with plant spacings on the basis of two years pooled data, whenever, number of branches and pod plant-1 were found non-significant. In case of fertility levelscrop produced significant number of branches, number of pods plant-1, 100 grain weight, seed yield, stalk yield, net return and benefit cost ratio on pooled basis. The interaction effects of plant spacings and fertilizer levels were found significant with seed yield and straw yield and also given significant net monetary returns and benefit cost ratio. On the basis of two years mean data highest seed yield (2270 kg ha-1), stalk yield (11470 kg ha-1), net monetary return (Rs. 44095.00 ha-1) and B:C ratio (2.24) were recorded, it may be due to higher number of plant population and application of high fertilizer dose (125% RDF).
