Abstract

Systematic surveys in garlic growing areas of HP viz., Bilaspur, Chamba, Una, Solan, Sirmour, Shimla, Mandi, Kullu, Kangra and Hamirpur districts were conducted during cropping season 2013-15 to assess the prevalence and distribution of Stemphylium blight of garlic under field conditions. The incidence of Stemphylium blight was found in almost all the districts surveyed. The average disease severity ranged between 31.2-70.0 per cent, maximum being at Kullu district (70.0%) and minimum at Shimla district (31.2%). The disease initially appears as a small spindle shaped white lesions on leaves, which later become sunken with a purple colour surrounded by a yellowish margin.

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

Lentil (Lens esculenta) is commonly known as masur and it is important pulse legume crop in India. Lentil has the ability to fix nitrogen and grow in marginal environments. The productivity of lentil is generally low in Bilaspur district of Himachal Pradesh, mainly due to lack of improved varieties and low technical knowhow. Therefore, the present study was conducted in the seventeen villages of district Bilaspur of Himachal Pradesh. Twenty five farmers’ fields were randomly selected and sown two high yielding improved varieties of lentil namely Vipasha and Markandey with one check variety already grown by the farmers. Among the varieties assessed, variety Vipasha proved to be the best with highest number of pods/plant (92.4) and minimum incidence of disease of 1.5 per cent resulting in the highest yield of 6.60 q/ha followed by Markandey with disease incidence of 2.1 per cent, 72.8 pods/plant and yield of 6.1 q/ ha. Hence, it was inferred that local variety must be replaced with Vipasha variety of lentil followed by Markandey.
