This study refers to a result of the study of the causality between agricultural mechanisation and grain production. It applied data from 280 prefecture-level cities across China from 2000 to 2018 with the SPDM model. This paper concludes that (1) when other conditions remain unchanged, the improvement of the level of agricultural mechanisation will not only significantly increase the local grain output but also have a noticeable spatial spill-over effect on the grain output of other regions through the cross-regional operation of agricultural machinery; (2) in the long run, the spatial spillover effect of agricultural mechanisation on grain production is greater and more evident than the direct effect; (3) the spatial spillover effect of agricultural mechanisation on grain production decreases with the increase of cross-regional distance.
Pruning is a technique used in orchards to control growth and stimulate the formation of new shoots and buds by removing dead or diseased wood. It has the common objectives of manipulating the vegetative or reproductive growth. The research work was carried out to quantify the pruning intensity and level on the quality and yield in Kinnow fruit crop was studied in Division of Fruit Science at Advanced Centre for Horticulture, SKUAST-J, Udheywalla Jammu, UT of J& K, India. The results showed that pruning had a substantial effect on the growth of kinnow plants and results in progressive increase in shoot length (0.88 m), shoot girth (2.42 cm), no. of leaves/shoot (43.27), no. of buds/shoot (60.55), time of emergence of shoot (9.29 days), no. of shoots produced (52.92), total no. of shoots (298.53) which were recorded with plants pruned @ 20 per cent intensity on 1st January while, highest fruit yield per tree (34.83 kg/plant) and and physico-chemical characteristics viz., number of fruits/plant (185.00), fruit length (6.18 cm), fruit breadth (6.60 cm), fruit weight (191.88 g), fruit volume (183.15 cc), juice (51.15 %), specific gravity (0.95), TSS (10.89o brix), acidity (1.39 percent), total Sugar (8.58 percent) and vitamin C (26.38 per 100 g of juice) were recorded highest with the kinnow trees pruned @ 20 per cent intensity on 15th January and appeared to be the best time and method to obtain maximum yield and quality of Kinnow fruit under north western shivalik regions of India.
The laboratory experiment on “Studies on effect of different soil types and moisture regimes on seed hydration value of various soybean varieties” was conducted during the season 2020-21 in CIC laboratory of Soil Science and Agricultural Chemistry Department, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, to find out the seed hydration value and germination in different soybean varieties at different soil moistures in three types of soil. This study was carried out in petri plates with four soybean varieties JS-335, MAUS-71, MAUS-158 and MAUS-162 at four soil moisture levels of 50, 75, 100 and 125 percent field capacities in Vertisols, Entisols and Inceptisols soils. The treatments were replicated two times in FCRD design and observations were taken at regular time interval of 6 hours up to 96 hours from sowing. The results obtained from investigation revealed that the germination parameters and seed hydration value for different soybean varieties were clearly influenced by different soil moistures in different soil types. Amongst all varieties, variety MAUS-162 showed highest germination at different soil moistures and lowest was noted in variety JS-335. In vertisols and Inceptisols, the highest seed hydration value was reported in variety MAUS-162 with earliest germination among all varieties in all soil types. Better germination for soybean varieties were observed at soil moisture of 75 and 100 percent field capacities. Vertisols and Inceptisols showed early and better germination for soybean seeds. Among all soybean varieties, MAUS-158 and MAUS-71 showed lower seed hydration value so can be suitable for rainfed cultivation.
Soil acidity is one of the major problems of South East Asia, especially India, Nepal, Srilanka, Bhutan, and adjoining areas. However, limiting is a costly practice managed through industrial and natural sources. Our study attempted to evaluate the effectiveness of three cheap and readily available liming materials viz paper mill sludge, calcium silicate, and stromatolite under laboratory conditions. Acid soil (pH-4.50) collected from Malkangiri, Odisha, was amended with liming materials following an utterly random design that consisted of six different treatment combinations replicated thrice. All the necessary observations were made on a fortnightly basis following standard procedures. The results indicated that amongst the liming material used, paper mill sludge application tremendously increased the soil pH from 6 to 7.1 when applied at an equal dose of the tested liming materials. The neutralizing value of Papermill sludge, stromatolyte, and calcium silicate was 60, 80, and 80 percent, respectively. Although liming is costly practice, it is also evident that regular liming is not pleasant for farmers and crops. Therefore, when employed, a double dose of lime requirements has shown skewed increment in soil reaction favouring farmer, crop, and soil environment as a whole. In the control treatment, no change occurred, but the application of F.Y.M. due to buffering property neutralized the exchange acidity, acidity due to Al+3, acidity due to H+ and raised the pH slightly. The application of liming materials at two doses neutralized the exchange acidity 1.10 to 0.62cmol(P+)/kg with calcium silicate followed by 1.12 to 0.90 cmol(P+)/kg withstromatolyte, followed by 1.12 to 0.90cmol(P+)/kg with paper mill sludge. The acidity due to Al+3 0.61 to 0.42cmol(P+)/kg withstromatolyte, followed by 0.61 to 0.50with calcium silicate, followed by 0.63 to 0.51cmol(P+)/kg with paper mill sludge. The acidity due to H+ 0.48 to 0.45cmol(P+)/kg withstromatolyte, followed by 0.46 to 0.38 cmol(P+)/kg with paper mill sludge followed by 0.46 to 0.12cmol(P+)/kg with calcium silicate. The pH from 5.0 to 5.9 withstromatolyte, followed by 5.2 to 6.0 with calcium silicate, followed by 5.0 to 6.1with paper mill sludge. The double dose of liming material @ 0.2 LR with F.Y.M. gives the highest pH and neutralization of H+& Al+3 compared to the single-dose @ 0.1 LR.
Genetic variability in available germplasm must be studied in order to develop improved cultivars through planned breeding programmes. As a result, the research work was carried out to evaluate the quality parameters of acid lime genotypes. Total of seventy lime genotypes were selected randomly from different areas of Jammu region. Results of the study revealed that among leaf characters most of the genotypes had medium colour of leaf blade and elliptic lamina shape. Among biochemical characters, highest TSS (8.890brix) was found in genotype JMU-Nag(70) and lowest TSS was observed in genotype JMU-Kat (14) (6.300brix). The genotype JMU-Log (4) had the lowest acidity (6.18 percent), while genotype JMU-Nag had the highest acidity (8.35 percent) (70). The highest content of ascorbic acid (36.81 mg/100ml juice) content was found in genotype JMU-Nag (70), maximum juice per cent (57.13 per cent) was recorded in the genotype JMU-Nag(70) and the highest pH (3.71) was observed in genotype JMU-Balli(62). Hence, the overall studies indicated that the genotype JMU-Nag(70), JMU-Jib(36) and JMU-Pana(41) being productive and superior in quality stands for selection and further improvement.
