In the present investigation 92 Avena genotypes were evaluated for multi-cut nature in randomized block design with three replications at the Research Farm area of forage Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi season. Highly significant differences observed by analysis of variance showed presence of high amount of variability for single cut and multi-cut. Correlation analysis indicated positive and significant correlations of green fodder yield with dry matter yield, plant height and number of tillers. Genotypes collected from different geographical areas had a role in the clustering pattern and cluster with highest inter-cluster distances were considered for hybridization as potential parents for obtaining high heterotic response. In single cut, the principal component analysis found three components with eigen values more than one and altogether explained 67.95% of the total accumulated variability. The first principal component explained 26.24% followed by second (21.84%) and third (19.87%). of the total variance while principal factor-3 (PF-3) showed regarded as fodder yield factors. In second cut, seven principal components had eigen values more than one and altogether explained 73.34% of the total accumulated variability. The first principal component explained 15.31 % of the total variation, followed by second, third, fourth, fifth, sixth and seventh principal components explained 11.94, 11.79, 10.54, 10.40, 7.38 and 5.97 % of the total variance, respectively, while PF-2 and PF-4 regarded as fodder yield factors for second cut of multi-cut oat.
Brinjal, Solanum melongena Linnaeus belongs to family solanaceae also known Eggplant or Baingan and it is the most important widely grown vegetable both for raw and cooked purpose and attack by the major and serious pest known asbrinjal shoot and fruit borer [Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae)] which is responsible for causing up to 37-100% damage as well as quality and quantity loss in brinjal. In order to manage this problem, farmers still depends on the pesticides, but excessive use of pesticides has resulted residues in the food chain, phytotoxicity, pesticide resistance, pest resurgence, bioaccumulation and secondary pest outbreak, in addition to causing harmful effect on the environment and non-targeted beneficial organisms. Here, we reviewed the sustainable approaches to reduce the incidence of brinjal shoot andfruit borer toachieve sustainability in brinjalproduction technology through the implementation of integrated approaches. We found that following major points have been reported to reduce the survival and damage of shoot and fruit borer: (1) use of resistant varieties (2) implementing a number of cultural practices, such as sowing time,plant density, inter/mixed/relay crops (coriander, clustrebean fennel, chilly, redhuni, radish, mint, onion, clover, fenugreek, maizeand African marigold), avoid ratooning of crop, collection and destruction of dried shoot tips and damaged fruits, mechanical practices as barriers and installing bird perches(3) monitoringthrough the pheromone traps(4) spraying repellent made up of neem seed kernel (NSK). Hence, integration of all these approaches in a unified manner has exposed more good results for sustainable management of shoot and fruit borer. This review highlights examples of successful management approaches from the past studies that were implemented in experimental trials and farmers’ fields. We concluded that an integrated approach is the most effective for long-term sustainable and eco-friendly management programs for shoot and fruit borer.
The plastic roller cup feeding and weighing mechanism of the automatic sowing and fertilizing drill was improved for sowing between wheat chickpea (2: 1) and wheat mustard (3: 1). Weighing rollers were selected based on seed shape and size and the number of cells in the periphery. Different types of seed flow from each cup feeding roller were achieved by splitting the seed hopper in separate compartments. For the selection of weighing mechanism, calibration was performed among the seven available cup feeding weighing rollers with different combinations of seed box exposure lengths. The improved intercropping seed drill was calibrated in the laboratory for the required seed rate. The seed rate for wheat-chickpea intercropping is 75 kg / ha for wheat with 4 rollers and 25 kg / ha for chickpeas with 5 rollers on a seed box exposure scale of 7. I found out. The required seed rate for wheat-mustard cropping is 75 kg / ha for wheat with 4 rollers and 6 kg / ha for mustard with 7 rollers on the seed box exposure scale. It turned out. The effective field capacity of the sowing and fertilizing drill for chickpeas was 0.42 ha / h, and that for the mustard mustard intercropping was 0.47 ha / h. As a result of agricultural studies, wheat-chickpea (2: 1) intercropping was performed better than wheat-mustard (3: 1) intercropping and single crops.
A single locking cotton feeder was designed to maintain a constant feed rate of individual pods at the ginning point of the double roller (DR) cotton gin. It consists of a pair of feed rollers, spike cylinders, grids, feed hoppers and distribution chutes. The spike cylinder has spikes, the tips of which are closer to the supply roller than the fixed thickness of cotton and have a ginning interval. The spike cylinder travels at a linear speed greater than the feed roller, whereby the cotton pods held between the feed rollers are hit by the spikes of the spike cylinder, thus ensuring a single locking of the cotton. The effect of single locking on the ginning efficiency of the DR cotton gin was investigated. The degree of unlocking was determined by measuring the change in cotton bulk density before and after passing through the feeder, which decreases with increasing spike cylinder speed. It was found that the DR cotton gin output was increased by 15 to 20% by adopting a single locking compared to the conventional feeding system consisting of an auto feeder and a micro feeder. Cotton quality was also found to improve in color grade. A single locking feeder has proved to be very useful in the cotton gin industry in India.
Maize harvest was a bottleneck for maize-scale production in the Huanghai Plain. Factors influencing the harvest of corn grains are: the biomechanical properties of corn and the technical parameters of the harvesting machine. In this study, we described how the threshing system is established in the combination of tangential flow and lateral axial flow. Shell grain damage rate was selected as the goal of this experimental study, and variation in the goal was investigated in relation to the biological properties of maize. Threshing experiments were performed to determine the effect of the main biological factor, the water content of the grains. After that, the main technical parameters were defined for the peripheral velocity of the threshing drum. The feed amount was economically maintained at 2.6 kg · s -1, and in this study, the threshing clearance was maintained at 36 mm for corn ears of average diameter. When the water content was 28% or less, the threshing ability of the tangential flow drum was similar to that of the axial flow drum. When the water content was 28% or more, the threshing ability of the tangential flow drum decreased significantly. When the water content is 24-26% and the peripheral velocity of the axial threshing drum is 17.28 m / s -1, the minimum value of the shell grain damage rate of the threshing system is 1.7%, which is the minimum value. there were.
