Integrated Crop Management To Enhance Vegetable Productivity And Farm Income Through Inm And Ipm Practices
Author:A.K. Singh And Ingita Gohain1
Volume: 12 | Issue no: 1-2017 | Pagination: 165-168
Vegetable production is an important component of agriculture and also an essential part of a balanced human diet. In recent years, vegetable production has also become an income generating enterprise for those farmers who are located close to markets and road sides. Local varieties and practices are of low productivity, prone to pests and grown without proper fertilizer management resulting in poor yield and poor soil fertility. Modern technologies are often inappropriate for them due to lack of knowledge and training. However, a combination of traditional and appropriate modern technology like INM, IPM and improved variety can reap the good harvest of vegetables and support livelihood and nutritional security of farmers. Considering the importance of vegetable production and to meet the market demand of tomato, chilli and brinjal crop, on-farm research trials (INM and IPM system) were conducted under IIHR-NE component programme during 2013-15 in South Tripura district of India.

Author:Mohammad Sabir, Devendra Singh1and Bhanwar Lal Jat2
Volume: 12 | Issue no: 1-2017 | Pagination: 141-159
Genotypic and phenotypic co-efficients of variation were high for average weight of clove, yield per plant, cloves per bulb and plant height. Width of clove, plant height and length of leaves, yield per plant, cloves per bulb, average weight of clove exhibited high heritability coupled with high genetic advance as per cent of mean. These characters are governed by additive gene effects. It was also concluded that selection on the basis of these characters will be more useful for the improvement of this crop towards attaining higher yield. Correlation co-efficient studies showed that phenotypic correlation co-efficients are higher than genotypic correlation which indicates the inherent association among the characters dependent of environment influence. Yield per plant had a positive and highly significant correlation with plant height, length of leaves, average weight of clove, equatorial diameter, polar diameter and clove/bulb which implies that these characters were contributing to bulb weight and bulb yield/plant. All the combination of traits should be considered while selecting for high yielding genotypes. Improvement of bulb weight per plant may be achieved by exercising direct selection of plant height, length of leaves, weight of cloves, equatorial diameter of bulb, clove weight, number of cloves per bulb, polar diameter of bulb and clove length as these exhibited significant positive direct effect on bulb weight per plant coupled with high heritability and high genetic advance as per cent of mean. Characters had correlation co-efficient value at par with their direct effect on bulb yield per hectare. In Mahalanobis D2 analysis, On the basis of Mahalanobis D2 values, all the 27 genotypes were grouped under study were grouped into six clusters. Cluster III (8), cluster V (6) and cluster VI (6) contained maximum number of genotypes and cluster I (4) and cluster II (2) comprising minimum number of genotypes and cluster IV contained single genotype.

Volume: 12 | Issue no: 1-2017 | Pagination: 136-140
The present investigation entitled diversity for shell seal in the natural population of walnut (Juglans regia L.) in the Kashmir valley was carried out in order to document the available genetic variability in walnut germplasm and to select elite walnut genotypes possessing superior attributes and quality traits. During the survey, data was recorded on one hundred fifty two (152) walnut trees growing in different areas of Kashmir valley. Remarkable variability was observed in seedling walnut trees for different morphological, nut and kernel characters. Similarly, variations were also reported for other characters viz., tree vigour, growth habit, branching habit, leaflet shape, shoot colour, nut shape, shell texture, shell colour, shell seal, shell strength, shell integrity, kernel shrivel and kernel colour. Studies on shell strangth revealed substantial variability among the seedling raised walnuts genotypes in Kashmir valley revealed that shell seal of walnut genotypes under the present study varied from weak to strong. Forty five genotypes (29.60%) were found to have weak shell seal; 60 genotypes (39.48%) had intermediate shell seal and 47 genotypes (30.92%) exhibited strong shell seal.

Volume: 12 | Issue no: 1-2017 | Pagination: 132-135
The present investigation on effect of media on growth parameters of banana cv. POOVAN was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University during 2014-2016. The experiment was conducted in Completely Randomized Design with 13 treatments in three replications. The treatments consisted of three growing media (FYM, Rice hull, Sawdust), two biofertilizers (Azospirillum and VAM) with sand alone as control. The results of the study revealed that the pseudostem height, pseudostem girth and number of leaves produced sucker-1 were favourably influenced by the treatment T7 (FYM + VAM) followed by T10 (FYM + Rice hull + VAM). Regarding root production, T8 (Rice hull + VAM) was found to be the best treatment. Further more survival percentage of plants was higher in the treatments in which FYM was used as the regeneration medium along with VAM.

Author:D. Ramesh Babu, D.K. Das Gupta1 And Sandeep Kumar Chauhan2
Volume: 12 | Issue no: 1-2017 | Pagination: 127-131
The rheological characteristics of musk melon (cantaloupe) pulp was evaluated with a view to determine its flow behaviour, yield stress and applicability of common rheological models. The experimental data on rheological behaviour were analyzed on the basis of four models viz., Ostwald, Casson, Bingham and Herschel-Bulkley (H-B). However, Herschel-Bulkley model showed best fit. Consistency index (K) was found to decrease with increase in temperature. The yield stress value determined by three methods showed in the range of 3.6 to 4.1 Pa. Yield stress calculated from stress-strain plot showed the maximum value. Overall the rheological behaviour of musk melon pulp followed the pseudo plastic with yield stress.

Volume: 12 | Issue no: 1-2017 | Pagination: 121-126
This experiment was held to study about the efficacy of concentration of plant bio regulators on vegetative growth, yield and quality characters of onion cv. NHRDF-RED-2 under Lucknow subtropical condition having dry climate and high pH soil (8.2). The experiment comprised of 13 treatments [Control (water spray), GA3 @ 50, 100 ppm, 150 ppm; NAA @ 50 ppm, 100 ppm, 150 ppm and combination of GA3 and NAA] laid out in the Randomized Block Design with three replications. The observations revealed that the application of T11 [GA3 @ 100 ppm + NAA @ 100 ppm] was better for improvement of growth i.e. plant height (76.50 cm), number of leaves (8.27), length of leaves (60.60) and basal diameter (2.05 cm) at 90 DAT. It also recorded the highest bulb yield (60.34 t/ha), fresh weight (90.51 g), dry weight (10.89 g), diameter (6.87 and 6.87 cm equatorial and polar, respectively) of onion bulb. Similarly, chemical properties like TSS (12.030 B) and pH (6.99) was found better under treatment T11 (GA3 @ 100 ppm + NAA @ 100 ppm) followed by T9 (GA3 @ 50 ppm + NAA @ 150 ppm). Thus, the study suggested that combined application of bio regulators (GA3 @ 100 ppm + NAA @ 100 ppm) may be followed to get better growth, yield and quality of onion cv. NHRDF-RED-2 under drier subtropical climate.
