Studies on economical seed yield of coriander (Corindrum sativum L.) as influenced by spacing and sowing time, under Akola condition

Appropriate planting time and spacing are the key factors towards production of more seed yield of coriander with high quality. Due to favorable agro-climatic conditions, farmers of Vidarbha region wants to grow coriander crop with diversification of existing cropping pattern of soybean-gram, cotton-chickpea. The experiment was conducted at Chilli and Vegetable Research Unit, Dr. PDKV., Akola, during rabi seasons of three consecutive years, starting from 2014-15 onwards. The experiment was conducted in Factorial Randomize Block Design with fifteen treatment combinations. The different five dates of sowing was first level of an experiment, starting from second fortnight of September i.e. 15th September (D1), 1st October (D2), 15th October (D3), 1st November (D4) and 15th November (D5). Another sub factor (S) of spacing with three levels i.e. (S1) close (30 x 30 cm), (S2) moderate (45 x 45 cm) and (S3) wider (60 x 60 cm). The result of the present experimentation reveals that, seed coriander crop sown on 15thOctober along with 45 X45 cm gave significantly better vegetative growth of the plant. However, significantly the maximum (12.96 q/ha) seed yield, along with good qualitative characters like number of umbels per plant, umbellats per umbel, seeds per umbels, test weight etc. as well as the maximum GMR, NMR and B:C ratio was obtained from the moderate spacing (45 x 45 cm) in between the rows and plant sown on second fortnight of October 15th (D3S2) combination.
