Performance of niger (guizotia abyssinica l. cass.) as influenced by various resource constraints

Niger (Guizotia abyssinica L. Cass.) is an important traditional oilseed crop of India, cultivated mainly in hilly and tribal areas. Inspite of high oil content and a wide range of adaptability, little attention has been paid towards maximization of this oilseed crop. Among the agronomic practices, fertilizer, thinning, weeding and plant protection play important role in maximizing the seed yield. Keeping in view all facts, the study of performance of niger as influenced by resource constraints was formulated in RBD design in three replications with 12 different treatments. The results in the present investigation revealed significant differences in respect of seed yield for all the treatments studied. Among the different treatments, highest seed yield was recorded by the treatment T1 (484 kg/ha) with B:C ratio 3.61 followed by T3 (451 kg/ha, BC ratio: 3.64) and T4 (414 kg/ha, BC ratio: 3.57) and lowest yield recorded by T12 (164 kg/ha).
