Abstract

The present study was based on primary data collected from a representative sample of 60 vegetable growers in Kullu District of Himachal Pradesh in order to examine the relationship of some socio-economic variables with productivity of selected vegetables. The study revealed that the female headed families were obtaining 10 to 18% higher productivities than male headed in case of cucumber, cauliflower, cabbage and pea. Families having size of more than 4 persons were obtaining higher yields in case of cauliflower, cabbage, tomato, Iceberg and cucumber. Further, higher yields in most of the vegetable crops were obtained by those households whose heads were in the age group of greater than 30 years. The educational-level of the head of the sample households was found to have a direct relationship with the productivity of all the vegetable crops. The marginal and small farmers were getting higher yield in vegetables than the farmers having more than 2 hectares of land. Regression analysis revealed that 1% increase in the area under crop would increase gross income of the farmers by 1.21% in case of pea crop. The study emphasized that the rural unemployed youth with education upto graduation should be encouraged to engage themselves in vegetable production as a profession.

Abstract

A field experiment was conducted at CSK HP Krishi Vishvavidyalaya, Rice and Wheat Research Centre, Malan during kharif 2016 to find out the bio-efficacy of new herbicide rinskor 2.5% EC in wet seeded rice (sowing of sprouted rice seeds in puddled fields). Four herbicide treatments comprising single herbicide rinskor at two doses (31.25 and 37.5 g a.i./ha 4-7 leaf stage of weeds), bispyribac sodium 30 g a.i./ha 3-4 leaf stage of weeds, and sequential application of pyrazosulfuron ethyl (25 g 3-5 days after sowing; DAS) followed by (fb) metsulfuron methyl + chlorimuron ethyl (4 g 25-30 DAS) were evaluated along with weed free (three hand weedings; 20 40 & 60 DAS), two hand weedings and weedy check. The crop was heavily infested with weeds (288.7/m²) viz., Monochoria vaginalis, Commelina benghalensis, Digitaria sanguinalis, Paspalum paspalodes, Echinochloa colona, E. crusgalli, Eleusine indica, Phyllanthus niruri and Setaria glauca, thus recording significantly more dry matter of both grass and broadleaf weeds compared to different weed control treatments. The weed index (increase in yield over weedy check) of different weed control treatments recorded values of 23.1 to 43.6 per cent; highest being with rinskor 37.5 g/ha. Rinskor at both the doses, bispyribac and sequential application of pyrazosulfuron ethy Jb metsulfuron ethyl + chlorimuron behaved alike in reducing weed density and were at par with two hand weedings. Rinskor and bispyribac were statistically equally effective in reducing dry matter of broad leaf weeds and were at par with weed free treatment. The significant effect of weed control treatments was reflected in growth and yield attributes of the crop. Rinskor 37.5 g/ha recorded tillering (336/m²) and panicles (320/m²) and grain (4.35 Mg/ha) at par with its lower dose (31.25 g/ha) and weed free treatment (weeding at 20,40 & 60 DAS). Thus, the new herbicide, rinskor 37.5 g/ha may be applied at 4-7 leaf stage of weeds (25 DAS) for efficient control of mixed weed flora in wet seeded rice.
