Design and experiment of key components for uniform fertilization of sweet potato ridge core
In view of the problems of large amount of fertilizer application, uneven application and inaccurate positioning of sweet potato fertilization machines at present in China, considering the distribution law of sweet potato roots and the characteristics of sweet potato planting patterns, a ridge-core arc-shaped uniform positioning fertilization technology was proposed in this paper. The arc shaper and spiral groove wheel fertilizer discharger are designed, the influencing factors that affect the uniformity of fertilization are analyzed, and the optimal working parameter range of the fertilizer discharger is determined. Furtherly, the rotation speed of the fertilizer discharge shaft, the spiral angle and the depth of groove are recognized as the test factors, the fertilizer discharge amount and the uniformity coefficient of variation of the fertilizer discharge are used as the indicators to carry out the quadratic regression rotation combination test. At the same time, the discrete element method is employed to simulate the process under different parameter combination settings, and the optimal parameter combination is obtained when the lift angle of the sheave is 79°, the groove depth is 3.7mm, and the speed of the fertilizer discharge shaft is 46r/min. Under the premise of the amount of fertilizer, the coefficient of variation of fertilizer discharge is smallest. By comparing with the actual operation effect, the simulation results are basically consistent with the field test conditions, which verifies the validity of the simulation test and the establishment of the regression model. This research can realize the uniform application of fertilizer in the ridge core at a certain depth and quantity, which can effectively reduce the amount of fertilizer application, improve the yield and the uniformity of sweet potato. At the same time, it provides a reference for the research and design of the sweet potato ridge core arc fertilization equipment.
Effect of Different Storage Containers on Incidence of Stored Insect Pests
The present investigation on “Effect of different storage containers on incidence of stored insect pests” was carried out by conducting a laboratory experiment by using various packaging materials viz. earthen pots, bags metal bins, glass bottles, plastic containers, porous HDPE bags, cloth bags, polythene bags of 700 gauge and gunny bags at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2019-20 and 2020-21. The results of the present study indicate that the polythene bags of 700 gauge treatment was recorded the significantly minimum mean per cent seed damage, weight loss and moisture content with 7.67 and 8.13; 15.61 and 16.33; and 13.43 and 13.52, respectively and the maximum mean per cent seed damage and moisture content with 30.27 and 29.53; 41.61 and 40.97; and 14.75 and 14.88, respectively in case of Sitotroga cerealella (O.) on maize and same results were also recorded Callosobruchus chinensis (L.) on blackgram and Rhyzopertha dominicia (F.) on wheat during the 2019-20 and 2020-21. Considering all the containers, the trend in the protection of stored cereals and pulses grains from insect population showed the following decreasing order, polythene bags of 700 gauge>plastic container>glass bottles>bags metal bins>porous HDPE bags>Cloth bags>gunny bag>earthen pod.
Correlation and Path Coefficient Analysis for Yield and Its Contributing Traits and other biochemical traits in Desi Cotton (Gossypium arboretum L.) Grown in Different Environment
The present study comprised of thirty Gossypium arboreum genotypes grown in two locations during the kharif seasons in the year 2016 and 2017 in a randomized block design (RBD) at CCS Haryana Agricultural University, Hisar and cotton research station, Sirsa, CCS Haryana Agricultural University. The observations on five randomly selected plants from each replication in each environment were recorded for morphological traits. Pooled mean data of four environments was subjected to examine variability parameters, such as coefficient of variation, association among seed cotton yield and component traits. Seed cotton yield per plant showed highly significant positive correlation with lint yield per plant, number of bolls per plant, boll weight, seed index, number of seeds per boll, number of monopods per plant, plant height, days to boll bursting and days to first flower. The path-coefficient analysis suggested the importance of lint yield per plant, number of bolls per plant, seed index, boll weight and plant height as they exhibited positive direct effects on seed cotton yield.
EPIDEMIOLOGY OF BACTERIAL LEAF BLIGHT OF RICE: REVIEW
The bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae is the most devastating disease that prevalent in all the rice growing areas of the world. The pathogen produced small water-soaked lesions, which later turn to yellowish white colour, elongated circular to quite uneven lesions. The most important factors for disease development are temperature, relative humidity, rainfall, sunshine hours and number of rainy days. Flooding and water logging conditions, not only cause wounds that hasten up infection and enhance severity of the BLB but also aid in the dissemination of the plant pathogen. BLB pathogen is highly variable in nature and continuous monitoring of its virulence profile is very important for breeding durable resistant varieties. Therefore, monitoring of pathotypes is helpful in evaluating the distribution patterns and composition of the dominant pathotypes. Various rice lines have resistance against Xoo under under epiphytotic conditions. RP 633-519-1-3-8-1, RP2151-173-1-8, BBL 180-5-1-4-1, IR 13610-72-2-2E-P1, IR 22082-41-2, C 702015 and IR 50400-64-1-2-2-2 are some superior line used in breeding programme for developing resistant.
Soil properties influenced by saline water and nitrogen fertilizer application under different irrigation methods in sandy soil
Irrigation with saline water is an alternative to alleviate freshwater shortages in arid and semi-arid regions. However, suitable and efficient irrigation management strategies are much needed for use of saline water as irrigation in agriculture. Necessary measures need to be taken to reduce the soil salinization and its effect on agricultural productivity and sustainability. An experiment was carried out in 2019 and 2020 to evaluate the effects of saline water and nitrogen fertilizer application under two different irrigation methods on soil properties and plant nutrition. The results showed that drip irrigation (DI) with water of high salinity could effectively increase soil moisture content and reduce salinity development in root zone as compared to surface flooding (SF). The soil moisture content in DI was higher than that in SF at surface layer, with increments of 9.4%, 20.3% and 6.8% for 60, 90 DAT and harvest (S1 treatment). The high salinity irrigation water (S3) with DI lowered the soil salinity by 37.4% (60 DAT) and 32.2% (90 DAT) at 0-15 cm depth over SF. The soil salinities at surface layer with S2 and S3 in DI were 2.09 and 3.64 dS/m, respectively, whereas those with SF were 3.59 and 5.36 dS/m. The SOC at surface layer was reduced by 6.3% and 12.5% with S2 and S3 treatment. The concentration of cations and anions in soil significantly increased with the higher salinity levels of irrigation water. The results showed the higher available NPK content (0-15cm) under DI i.e., 126.2 kg ha-1, 29.8 kg ha-1 and 253.5 kg ha-1 and it reduced with saline water treatment except available K in soil. The saline water treatment (S2 and S3) reduced the total NPK content in plant and fruit. Application of 25% higher N rate (N3) over irrigation method and saline water levels increased the total NPK content but it was found to be at par with N2. These results suggest that drip irrigation can be used over traditional method for better soil profile moisture, decreased soil salinity and reduced salinity effects on soil and plant.
