Influence of Weed Management and Phosphorus Fertilization on Nutrient content, Uptake and Biochemical Parameters of Cowpea [Vigna unguiculata (L.) Walp.]
A field experimentation was undertaken during kharif 2019 at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur to study the influence of weed management and phosphorus fertilization on nutrient content, uptake and biochemical parameters of cowpea (Vigna unguiculata (L.) Walp.). Outcome of this research revealed that maximum chlorophyll content, seed protein content, nitrogen and phosphorus content of seed and haulm and their uptake by seed, haulm and total uptake by cowpea crop were recorded with pre-emergence application of pendimethalin 750 g ha-1 in combination with imazethapyr + imazamox 33.75 g ha-1 as post-emergence at 15-20 DAS next to weed free treatment. Whereas, application of phosphorus at various doses influenced chlorophyll content, seed protein content, nitrogen and phosphorus content of seed and haulm and their uptake by seed, haulm and total uptake by cowpea crop significantly.
Performance of chickpea under pigeonpea based sequential intercropping systems and integrated nutrient management in black soils of Telangana state, India
An experiment was carried out during kharif and rabi seasons of 2019-20 and 2020-21 at ARI, Rajendranagar, Hyderabad. The experiment was laid out in randomized block design (Factorial) with two factors i.e., one with six levels of sequential intercropping systems of pigeonpea (S1 to S6) and other with two levels of nutrient management practices (N1 – Recommended dose of fertilizers and N2 - an integrated approach). A separate sole cropped treatment of chickpea (S) was sown under both the nutrient management practices to compare the chickpea under sequential intercropping systems and sole cropping. For chickpea, only 75 per cent of recommended dose of nitrogen was applied to the both the nutrient management practices. Initial and final plant population recorded higher when chickpea sown as sole (S). Sole planting of chickpea (S) and integrated nutrient management (N2) recorded higher plant height, leaf area, dry matter production plant-1, number of pods plant-1, seed yield, stalk yield and N, P, K uptake than chickpea in sequential intercropping systems (S3 and S5) during both the years. Similarly, when we compare the chickpea in sequential intercropping systems (S3 and S5), these parameters recorded higher when chickpea sown in S5 than S3. Test weight, number of seeds pod-1 and harvest index were not influenced by the either sequential intercropping system nor integrated nutrient management. From the above studies, it can be concluded that when chickpea sown as sequential intercrop with paired row system of pigeonpea resulted the higher growth, yield and nutrient uptake of chickpea than chickpea in sequential intercropped with normal spaced pigeonpea.
Research on the Fusion Technology of Renewable Energy and Agricultural Non-Point Source Pollution Prevention and Control
Agricultural non-point source pollution has the characteristics of complex occurrence mechanism and wide space-time range. The randomness of the time and place, occurrence of intermittent mode, uncertainty of emission form and way have increased the difficulty of agricultural non-point source pollution prevention and control. Based on the analysis of three stages of agricultural non-point source pollution prevention and control, the characteristics of the renewable energy technology and its specific methods of fusion technique combined with agricultural non-point source pollution prevention and control system were described in detail in this paper. Meanwhile, the scarcities of renewable energy technology applied in agriculture non-point source pollution prevention and control were pointed out and the important role of the renewable energy technology in agriculture non-point source pollution prevention and control were emphasized. According to this, this paper aimed at the deficiency of biogas technology and monitoring methods, two kinds of specific solutions were proposed and the advantages and disadvantages of two kinds of schemes were analyzed, respectively. The research work in this paper is of great guidance for the renewable energy technology applied in future agricultural non-point source pollution.
Design and Experiment of Flexible Threshing Device for Cabbage Seeds
In order to solve the technical problems of high rate of breaking and un-threshing in the threshing process of cabbage seeds, based on the conventional spike teeth- grid concave threshing unit, a low damage threshing unit with the combination of flexible spike teeth with round heads and a concave with circular tubes was designed. In this study, Hertz contact and collision theory was used to analyze and determine the structural parameters of the new threshing unit. The interaction force of different threshing elements, concave and materials were analyzed by using discrete element method. The feasibility of the flexible threshing unit was verified by the comparison test of the distribution of threshed mixture. Finally, in the orthogonal experiment, the rotating speed of the cylinder, the concave clearance and the feeding rate were taken as the experimental factors, and the breaking rate and the un-threshing rate of the Chinese cabbage seeds were taken as the experimental indexes, the optimal working parameter combination of the threshing unit was obtained by using the weight matrix method. Under the condition the rotating speed of the threshing cylinder 750 rpm, the concave clearance 20 mm, and the feeding rate 1.4 kg/s, the threshing performance of the flexible threshing unit was the best. At this time, the breaking rate was 0.064%, and the un-threshing rate was 0.67%, which both met the relevant industry standards.
Residue and field efficacy of selected insecticides against diamondback moth (Plutella xylostella L.) on cabbage
The field efficacy of chosen insecticides was studied during two consecutive years showed that chlorantraniliprole 18.5 SC was incredibly effective insecticide in managing the population of diamond back moth, Plutella xylostella Linnaeus on cabbage, Brassica oleracea var. capitata and significantly differed with spinosad 2.5 SC. Residue analysis of chlorantraniliprole 18.5 SC was estimated at recommended and doubles the recommended dose on cabbage crop to study its dissipation behaviour. The average initial residues of chlorantraniliprole 18.5 SC was varied from 0.379 to 0.021 mg kg -1 and dissipated 80.21 % after 5th day of application at recommended dose and 0.828 to 0.053 mg kg-1 with 93.59 % dissipation after 10th day of application at double the recommended dose, respectively. The half-life values at recommended and double the recommended dose were 1.05 and 1.41 days, respectively. At 10th and 15th day residues of chlorantraniliprole were below limit of quantification (0.01mg kg-1) after application and below maximum residue limit (0.03 mg kg-1) at 7th and 15th day at recommended and double the recommended dose, respectively.
