Growth and yield of niger (Guizotia abyssinica L.f. Cass) as influenced by different land configuration and varieties

Abstract

A field experiment was conducted during Kharif 2024 at the Experimental Farm of Agronomy Section, College of Agricultural Biotechnology, Latur, to study the Effect of land configuration on growth and yield of niger (Guizotia abyssinica L.) variety in kharif season. The soil was clayey in texture, moderately alkaline, low in available phosphorus, moderate in nitrogen and high in potassium. The experiment was laid out in a Split Plot Design with three land configuration Flat bed, Ridges and Furrow and Broad Bed Furrow three varieties PNS-6, Phule Karala, and Phule Vaitarna. Result revealed that BBF land configuration recorded significantly highest growth attributes plant height (161.72 cm), number of functional leaves per plant (36.36), number of branches per plant (9.16), leaf area per plant (17.14) and dry matter accumulation (13.29) This is might be due to favourable seed bed, aeration, more conservation of water in broad bed furrow and was at par with Ridges and Furrow where as least in flat bed. BBF also recorded highest yield attributes viz. number of seeds per capsule (26.58) seed yield (539 kg ha-1), stalk yield (3785 kg ha-1), biological yield (4324kg ha-1) and harvest index (12.46%) and was at par with Ridges and Furrow where as least in flat bed. Phule Vaitarna recorded significantly highest growth attributes viz. plant height (159.46 cm), number of functional leaves per plant (35.69), number of branches per plant (9.07), leaf area per plant (17.11dm-2) and dry matter accumulation (12.80) and was at par with Phule karala and least at PNS-6. Phule Vaitarna also recorded highest yield attributes viz. highest yield attributes viz. seed yield, number of seed per capsule, stalk yield, biological yield and harvest index.
