Abstract

Black gram (V. mungo) is one of the important pulse crops in India which plays an important role in supplementing the income of small and marginal farmers. Non adoption of improved varieties and recommended practices is one of the reasons for low productivity in this crop. Improved technological package was compared with that of farmers' practice in the Bilaspur district of Himachal Pradesh during kharif 2006 to 2009. The results revealed that the use of improved variety, line sowing and balanced application of fertilizers under the improved practice increased seed yield of mash by 34.1 to 81.6% over farmer practice. Improved technological package gave 33.7% higher gross return and 70.4% higher net return over the prevalent practice of the farmers. The average additional cost and additional net return of INR 3003 and INR 10715 were recorded from 2006 to 2009. Incremental benefit cost ratio (IBCR) ranged from 3.10 to 4.64 with an average value of 3.55. The water use efficiency has also been increased by using the improved agricultural technologies in the demonstrations.

Abstract

Onion occupies an important place in daily diet and is semi-perishable in nature. The production of off-season onion in Kharif season in North Indian plains can stabilize the market supply of fresh onion as well as its price in winter and spring seasons. Keeping this in view, the present investigation was carried out at the experimental farm of Krishi Vigyan Kendra, Bilaspur, Himachal Pradesh during 2013 and 2014. Two varieties namely, N-53 and Agrifound Dark Red (AFDR) were evaluated using sets and seedlings following randomized block design in four replications along with Farmer practice (FP). The marketable bulb yield of both the varieties raised through sets was significantly higher than those raised from seedlings during both the years. The higher bulb yield was the result of low mortality of seedlings and improved crop stand which resulted in higher economic returns. In another experiment on weed management practices, pre- emergence application of alachlor and pendimethalin @ 1.00 kg a.i. /ha, respectively along with hand weeding at 40 days after planting resulted in significantly higher bulb yield compared to their sole application. Hence, Kharif onion crop raised through sets of AFDR variety followed by N-53 is better than seedling raised crop under low hill conditions of Himachal Pradesh.

Abstract

Realizing the importance of cluster frontline demonstrations in transfer of latest technologies, Krishi Vigyan Kendra are regularly conducting CFLDs on pulse crops at farmer's field with the objective of convincing farmers and extension functionaries together about the production potentialities of production technologies for further wide scale diffusion. To boost the production and productivity of chickpea pulse crop and to find out the yield gap, a total of 312 numbers of cluster frontline demonstrations on chickpea were conducted in 156 numbers of adopted villages of the four blocks of the Bilaspur district of Himachal Pradesh under rainfed conditions for consecutive 4 years (2015-16 to 2018-19). For comparison with recommended practices prevailing farmers' practices were treated as control. The findings of the study revealed that irrespective of the chickpea varieties used in demonstrations, percent increase in demonstrations yield over farmers practice ranged from 24.6 to 95.1 per cent. It was further observed that in terms of economics chickpea crop recorded higher net returns per hectare in demonstration plots compared to farmer's practice during all the years of studies. The extension gap and technological gap ranged between1.5-5.9 q/ha and 0.9-12.4 q/ha, respectively. The benefit cost ratio which indicates that whether CFLD technology is profitable or not varied from 2.22, to 3.8 during the study period and was always higher in demonstrations plots over farmers practice. The per cent technology index varied from 6.92 to 51.67 per cent indicating urgent need to make aware and motivate the farmers to adopt improved and economically viable technologies for chickpea production.

Abstract

The experiment was conducted at Krishi Vigyan Kendra, Bilaspur during 2017-18 and 2018-19 to find out alternatives to manual weeding in elephant foot yam. The manual weeding and herbicides alone and in combinations were tried. The results revealed that pre emergence application of alachlor @1.00 kg a.i./ha along with hand weeding after 60 days of planting is the most effective and economic treatment for weed management and getting highest return in elephant foot yam variety 'Palam Zimikand-1' under low hill condition of Himachal Pradesh.

Abstract

The present investigation was carried out at the Experimental Farm of Krishi Vigyan Kendra, Bilaspur, Himachal Pradesh for two consecutive years 2017-18 and 2018-19 to study the effect of curing methods on shelf life of onion bulbs, harvested at their physiological maturity, cured with and without leaves and dried in shade in a well ventilated airy room. The Kharif onion bulbs kept for curing alongwith 12-15 cm tops, dried from top towards bulbs, leading to retaining their proper shape, size and bulbs remains compact which leads to prolonged shelf life of bulbs, whereas, 40 per cent sprouting was observed in bulbs kept for curing without tops and they become loose and cannot be kept for further storage.

Abstract

The investigation was conducted during Kharif, 2020 at Research Farm of Research Sub Station Berthin, District Bilaspur, Himachal Pradeshin which 26 genotypes, collected within and outside the state were evaluated for yield and quality attributes in a Randomized Complete Block Design (RBD) with 3 replications. The promising genotypes identified based on mean performance for yield and quality attributes are LC-10 (collection from Baijnath of district Kangra, HP)was found best for highest total yield, cormel yield, cormel diameter, corm yield, number of cormels /plant, sugar and starch content (7 characters) followed by LC-15 (collection from Kolar of district Sirmour, HP)for total yield, cormel yield, cormel diameter, corm yield, crude protein and lowest oxalate content (6characters); LC-8 (collection form Gagret, Tehsil Amb of district Una, HP)recorded highest total yield, cormel yield, number of cormels /plant and total polyphenols (4 characters); LC-14(collection from Sarkaghat of district Mandi, HP) for total yield, cormelyield andnumber of cormels /plant (3 characters), LC-9 (collection from Village Bassi of district Mandi) for total yield, cormel yield and total polyphenols (3 characters). Based on the performance of these genotypes, they can be utilized as source of germplasm in colocasia improvement program under natural farming conditions.
