The study was conducted in Khowai district of Tripura with randomly selected True Potato Seed (TPS) growers. TPS can serve as a great alternative to the seed tubers in the hilly state of Tripura as only 100 g TPS is needed for one ha. of land as compared to nearly 2 tones of seed tubers required to plant in the same area. TPS can be used as a suitable alternative technology of potato cultivation in the state to improve the productivity and reduce the cost of production. The technological need of the majority of the TPS growers, i.e., 87.50 per cent was plant protection measures with rank I. The other technological need observed were post harvest treatment (79.17 %) which includes application of boric acid, sorting and grading, packing, curing etc. and method of fertilizer application (76.67 %) with II and III rank respectively. So, it is utmost necessary that the agricultural extension workers through regular trainings on plant protection measures with the TPS growers should guide the farmers to get optimum yield per unit area by effective management of pests and diseases.

SummaryThirty-two experiments examining the effects of the weight and within-row spacing of potato seed tubers on graded tuber yields of five varieties were conducted on eight sites from 1980 to 1985. A complex analysis technique was used to combine these data and estimate the optimum tuber planting densities for different ratios of seed cost to small (40–60 mm) and large (60–80 mm) ware value. The same technique could be applied to any other combination of seed cost, ware size and ware value.The optimum tuber planting density decreased with increasing seed-tuber weight. Differences in optimum planting density between varieties were much greater with small (35 g) than with large (105 g) seed tubers and decreased as the cost of seed increased relative to the value of ware. As large ware became worth more than small ware the influence of increasing seed cost on the optimum density was reduced. As the value of large ware increased, net returns increased and the effect of seed cost on net returns was reduced. Mean tuber size decreased with increasing stem density at harvest and at the same stem density was lower in varieties producing more daughter tubers/stem. Changes of mean tuber size (μ) and the spread of yield across size grades (σ) with time were well described by parallel curves in different varieties. It is suggested that in future it may not be necessary to determine optimum tuber planting densities by complex experiments involving several seed-tuber weights and spacings. Instead μ and σ could be estimated from simple experiments and tuber spacings determined by comparison with control varieties.

SUMMARYSeedling tubers of three true potato seed (TPS) crosses raised in a seedbed soil mixture of clay, sand and dry leaves produced about 3.1 kg of seedling tubers m−2 in the growing season of 1988–89 and between 4.3 and 5.1 kg m−2 in 1989/90. The seedling tubers produced were stored and their use as seed tubers was subsequently compared with the locally popular variety Alpha. The mean tuber yields of the hybrids ranged between 9.4 and 11 t ha−1 in 1990/91 and between 21.9 and 22.9 t ha−1 in 1991/92. Mean tuber yields of cultivar Alpha were 14.3 t ha−1 in 1990/91 and 24.1 t ha−1 in 1991/92, showing that tuber yields comparable to those of imported seed tubers could be obtained from seedling tubers of TPS origin.

A field study was carried out at Khumaltar-Lalitpur, during 2002-2004 to evaluate and comparethe performance of different sizes of seedling tubers (1-5 g, 5-10 g, 10-20 g and 20-40 g) of truepotato seed (TPS) with whole and half cut seed tubers of Desiree of 20-40 g size at 60- × 25-cmspacing. Percent emergence, plant height, ground cover by foliage, stems/plant, number of tubersper plant, marketable and total yields were significantly increased with the increase in seedlingtubers weight as compared to whole and half cut seed tubers of Desiree. Late blight(Phytophthora infestans L.) disease was quite low in the TPS crops than Desiree. Both wholeand half cut seed tubers of Desiree produced significantly higher average per tuber weight.Uniformity of the tubers harvested from different sizes of seedling tubers was statisticallysimilar and tubers from Desiree were statistically uniform as compared to seedling tubers. Thethree years result suggests that more than 1 g size seedling tubers can be successfully used forpotato production as from the seed tubers of any standard variety.Key words: Desiree; seedling tuber; tuber size; tuber yieldDOI: 10.3126/narj.v6i0.3341Nepal Agriculture Research Journal Vol.6 2005 pp.28-34

The main objective of this study was to determine the extent of adoption of improved potato production technologies by the potato growers. Data were collected from 231 potato growers of three highly concentrated potato growing Upazilas, namely Pirgachha (Rangpur), Munshiganj Sadar (Munshiganj), and Shibganj (Bogra) during October 2010 to February 2011. The potato growers showed marked individual differences in their socio-economic characteristics and majority of them belonged to middle age category having small family size, primary level of education, small farm size, medium innovativeness, and medium contact with extension personnel. The study revealed that highest proportion of the respondents in Munshiganj Sadar belonged to high adoption category in case of BARI recommended potato variety (72.6%), optimum planting time (87.7%), use of balanced fertilizers (45.2%), whereas medium adoption categories were found in quality potato seed (52.1%), proper seed size (47.9%), fertilizer application methods (71.2%), optimum irrigation (89%), earthing up (84.9%), plant protection (74%), and low adoption categories were found in maintaining proper spacing (42.5%). In Pirganj of Rangpur, highest proportion of the respondents belonged to high adoption category in case of BARI recommended potato variety (77%), optimum planting time (83.8%), whereas medium adoption categories were found in the use of quality potato seed (64.9%), balanced fertilizer (43.2%), proper seed size (52.7%), fertilizer application methods (87.8%), optimum irrigation (97.3%), earthing up (86.5%), plant protection (93.2%), and low adoption categories were found in maintaining proper spacing (64.9%). In Shibganj of Bogra, highest proportion of the respondents were found in high adoption category in case of BARI recommended potato variety (75%), optimum planting time (86.9%), whereas medium adoption categories were found in use of quality potato seed (52.4%), balanced fertilizers (47.6%), fertilizer application methods (78.6%), optimum irrigation (95.2%), earthing up (88.1%), plant protection (76.2%), and low adoption categories were found in maintaining proper spacing (59.5%) and proper seed size (57.1%). The study also revealed that highest (53.4%) proportion of the respondents in Munshiganj Sadar belonged to high potato yield (above 29 ton/ha) farmer category while medium potato yield (between 19 to 29 t/ha) category were found in other two areas i.e., Shibganj (58.80%) and Pirgachha (79.50%). Education, farm size, subsistence pressure, annual income, contact with the sources of information, farming experience, attitude, and knowledge on potato production showed significant positive relationship with adoption of improved potato production technologies.

The study was conducted in Chellampatti block of Madurai district in Tamil Nadu among 90 vegetable growers to assess the knowledge and extent of adoption of recommended vegetable cultivation practices. Interview schedule was constructed, pre-tested and finalized and used for collecting data. From the findings of the study it could be found that the average knowledge of vegetable farmers on recommended technologies was 74.72 per cent. Method of transplanting, recommended variety and HYV, fertilizer application, weed management, mulching and seed treatment practices were known to the farmers ranging from 75 to 90 per cent. Overall adoption level of farmers on technologies was 55.27 per cent. Soil testing, SHC recommendations, growth regulators, mulching, foliar spray, plant protection measures were having low adoption ranging from 40-48 per cent. Rise in fertilizer and pesticide prices, unavailability of timely and quality inputs, lack of knowledge to identify pest and diseases, lack of communication and training cum demonstrations on improved practices were felt by 35-45 per cent of the farmers as constraints for yield gap. The extension system have to popularize the recommended technological packages in fields through effective training, demonstrations, field visits, monitoring, etc. which helps to reduce yield gaps and thereby increasing the productivity of crops.
