Abstract
A field experiment was conducted on sandy loam soil of Agronomy Farm, Gujarat Agricultural University, Anand Campus, Anand during the rabi season of the year 1991-92 to study the "Effect of Sowing/ Transplanting Methods, Sowing time. Row Spacing and Fertilizer Levels on Yield of Mustard [Brassica juncea (L.) Czern and Coss]". Twentyfour treatments comprising of all possible combinations of two levels of sowing dates viz., 25th October and 14th November, two methods of sowing viz., Drilling and Transplanting, two spacings viz., 30cm x 10cm and 45cm x 10cm and three levels of fertilizer viz., 25 + 25+0 NPK kg/ha, 50 + 50 + 0 NPK kg/ha and 75 + 75 + 0 NPK kg/ha were tried in split plot design with four replications. Sowing dates, methods of sowing and spacing were relegated to the main plots whereas fertilizers levels were taken as subplot treatments. The results indicated that the plant height, number of primary and secondary branches/plant, number of pods/plant, seeds/pod, seed weight and test weight were significantly more under 25th October sowing than the later sowing (14th November). The mustard seed and stover yields were also higher under early sown crop than the sowing at later date. Sowing on 25th October (2325 kg/ha) gave 42.28 per cent higher seed yield over 14th November (1634 kg/ha) sown crop. Maximum net profit of Rs. 15715/ha was obtained with 25th October sown crop. Drilling method of sowing recorded appreciably higher plant height, number of primary and secondary branches/plant, number of pods/ plant, number of pods/plant, seeds/pod, seed weight and test weight and also the seed and stover yields. The seed yield recorded with drilling method (2221 kg/ha) was 27.71 per cent higher than the transplanted crop. The drilling method also recorded maximum net profit of Rs. 14936/ha. Different levels of spacing viz., 30cm x 10cm and 45cm x 10cm were significantly superior for all growth as well as yield attributes and stover yield but seed yield of mustard was not significantly changed due to spacing. However, net profit obtained under both the spacings was almost identical. Fertilizing mustard with 75 + 75 + 0 NPK kg/ha recorded significantly higher plant height, number of primary and secondary branches/ plant, number of pods/plant, seeds/pod, seed weight, test weight and seed and stover yields over lower levels of fertilizers. The seed yield (2206 kg/ ha) recorded with 75 + 75 + 0 NPK kg/ha was 31.46 and 7.29 per cent higher over 25 + 25 + 0 NPK kg/ha and 50 + 50 + 0 NPK kg/ha, respectively. This level of fertilizer also recorded maximum net profit of Rs.9562/ha and was found to be optimum. Sowing on 25th October produced significantly higher oil yield (917 kg/ha) than 14th November sown crop. Early sown crop (25th October gave 42.83 per cent higher oil yield over 14th November sown crop. But oil content of seed was not affected significantly due to sowing time. Between methods of sowing /planting, drilling gave significantly higher oil yield (873 kg/ha) than the transplanting. The percent increase in oil yield was 27.44 under drilled crop over transplanted one. However, oil content was not significantly affected due to different methods of sowing. Different levels of spacing did not make significant variation in oil content and oil yield of mustard crop. Application of 75 + 75 + 0 NPK kg/ha gave significantly higher oil yield (854 kg/ha) of mustard. Contrary to the above findings oil content was found to decrease with the increase in levels of fertilizer application. Based on the results from one year experimentation, it seems quite logical to indicate that potential production and profit from mustard crop can be secured by sowing on 25th October by adopting drilled method spaced at 30cm or 45cm row spacing and fertilized with 75 + 75 + 0 NPK kg/ha on loamy sand soil of middle Gujarat.
