Yield Gap Analysis of Rapeseed (Brassica campestris var. Toria) in Kokrajhar District of Assam, India

The present study was carried out at five different villages of Kokrajhar district of Assam where cluster front line demonstration (CFLD) of High Yielding Variety (HYV) of rape seed (TS 46) was conducted by Krishi Vigyan Kendra, Kokrajhar. A total of 652 nos. of front line demonstration (FLD)s were evaluated to find out the yield gaps between HYV toria variety TS 46 and variety grown by farmers. Yield data of both demonstration and farmers practice were recorded and their yield gap, technology gap, extension gap and technology index were analyzed. The yield of rape seed variety TS 46 was registered 22.38 to 50.00 per cent higher over farmer’s variety. On an average technology gap, extension gap and technology index were recorded as 2.28qha-1, 2.08 qha-1 and 20.73 per cent respectively.

The present study was carried out in four different villages under Longleng district of Nagaland, India. KVK, Longleng conducted a frontline demonstration of HYV of toria (TS 36). A total of 32 nos. of FLDs were evaluated to find out the yield gaps between HYV toria variety TS 36 and variety grown by farmers. Yield data of both demonstration and farmers practice were recorded and their yield gap, technology gap, extension gap and technology index were analyzed. Results revealed that the Toria yield (Cv. TS 36) was recorded 40.6 to 40.7 per cent higher over farmer’s variety. On an average, technology gap was recorded 4.10 q/ha, while the average extension gap was recorded 2.40 q/ha. Average technology index was recorded 34.10 percent. Average net return was found Rs.15375.50/ha and Rs.8637.50/ha with demonstration and farmers practice respectively. Higher benefit-cost ratio, production efficiency and economic efficiency were recorded in the demonstration plot than the farmer's practice.

Yield Gap Analysis

Demonstrations (Improved Practice-IP) on wheat variety GW-273 were conducted on farmers’ fields in Villages Bichhua and Sanjari of Kundam Block of Jabalpur district during rabi season of the year 2014-15. Prevailing farmers’ practices were treated as control for comparison with recommended practices. About 29.98 per cent higher grain yield was recorded under demonstrations over the farmers’ practices (Farmer Practice-FP). The average extension gap, technology gap and technology index were observed to be 7.34 q ha-1, 11.41 q ha-1 and 0.25, respectively. The study found, the yield of wheat in IP under irrigated conditions ranges from 24.20 to 42.20 q/ha whereas in FP it ranges between 16.72 to 38.93 q ha-1. The per cent increase in yield with IP over FP was recorded in the range of 0.05 to 76.68. The extension gap and technological index were ranging between 0.02-17.62 q/ha-1 and 0.06-0.46, respectively.

Yield Gap Analysis

The present study was conducted at farmers’ field in Narsinghpur and Umaria districts of Madhya Pradesh; Wardha and Yavatmal districts in Maharashtra during 2016 to 2017. The results of yield gap analysis from a sample size of 160 farmers revealed that the average yield gap-I (technology gap) for pigeon pea and chickpea was 712 to 817 kg/ha and 755 to 789 kg/ha in Madhya Pradesh and in Maharashtra 500 to 657 kg/ha and 395 to 627kg/ha. While, the average yield gap-II (extension gap) for pigeon pea was relatively lower i.e. 426 to 448 kg/ha in Madhya Pradesh and 454 to 558 kg/ha in Maharashtra. Whereas, the average yield gap-II for chickpea was relatively lower i.e. 264 to 421 kg/ha in Madhya Pradesh and 427 to 518 kg/ha in Maharashtra. However, the overall yield gap analysis in pulses in both the district of Madhya Pradesh found that technology gaps (gap-I) were observed more than extension gap (gap-II) in varieties of both the crop. In case of both the district of Maharashtra found that technology gaps (gap-I) were observed less than extension gap (gap-II) in varieties of both the crops except variety Jaki 9218 of chickpea and ICPL 8863 variety of pigeon pea. Therefore, it is summarized that technology gap in pulses (pigeon pea and chickpea) was more than extension gap at farmers field. The potential interventions and various constraints of yield gap in major pulses have been highlighted in this paper.
