Background: Greengram is an important short duration crop for rainfed area of Telangana state. Green gram is grown widely for human diet which contains 25 % protein, 60 % carbohydrate, 1.3 % fat and several essential amino acid including lysine and easily digestable. It is also rich in Vitamin A, B1, B2 C and calcium, phosphorus and potassium. Sowing of seed, application of fertilizers and intercultivation operations should be done timely to get the higher yields and monetary returns besides saving of time and labour, which is possible through only by mechanization in greengram. Methods: This experiment was conducted during Kharif season of 2017 and 2018 at Agricultural Research Station, Madhira farm, Professor Jayashankar Telangana Agricultural University, Hyderabad (Telangana). The soil of the experimental field was clay loam soil in texture, having alkaline reaction (pH=8.3), EC=0.33 ds m-1, low organic carbon (0.18%) and having low available nitrogen (153 kg ha-1), medium in available phosphorus (42 kg ha-1) and high in available potassium (538 kg ha-1). This experiment comprising of two treatments i.e., selective mechanization and normal practice, which was tested by simple t-test at 5% level of significance, non-replicated. Result: Sowing of seed and fertilizer application through seed cum fertilizer drill and intercultivation by tractor drawn implements has shown in good crop growth inturn to get the higher yields and monetary returns besides saving of labour and time in greengram cultivation.

The study was conducted with the objectives to prepare and formulate a multi nutrient stick and to evaluate and compare its effect on oriental pickling melon with fertigation. The investigation was carried out in two parts: formulation of nutrient stick and field experiment using oriental pickling melon. The trials were conducted at College of Agriculture, Padannakkad and Regional Agricultural Research Station, Pilicode during 2016-18. The nutrient stick was formulated as per the nutrient requirement of oriental pickling melon. The nutrient release studies conducted using nutrient stick proved it to be suitable for soil application. A field experiment was carried out in randomized block design with nine treatments and three replications. The treatment combination with foliar silicon spray was found to be highly effective to the crop in terms of quality and yield parameters. The residual available soil nutrients especially nitrogen, phosphorus and potassium were higher in treatments with fertigation as compared to fertilizer application in the form of nutrient stick, which indicated better efficiency of nutrient sticks. These results clearly indicated the suitability of fertilizer application in the form of nutrient stick along with drip irrigation.

SummaryAn experiment was made on a clay loam soil to compare direct drilling, shallow cultivation and ploughing for spring barley over a period of 3 years (1975–7). At a uniform rate of fertilizer application (75 kg N, 40 kg P2O6, 40 K2O/ha) combined drilled with the seed, the mean grain yields over 3 years were 5·89, 6·07 and 6·13 t/ha, respectively, direct drilling producing significantly less grain than shallow cultivation or ploughing in 1975 only.For 1975 and 1976 the mean uptake of nitrogen by shoots of barley at anthesis was 25 kg N/ha less after direct drilling than after ploughing but in 1977 there was no difference. The smaller uptake of nitrogen by direct-drilled barley in 1976 was more likely caused by less available nitrogen in the soil than by smaller root systems. Soil strength (cone resistance) and soil bulk density of the direct-drilled treatments were greater than those of the ploughed and shallow cultivated. Although concentration gradients of extractable phosphorus and potassium formed in direct-drilled and shallow-cultivated soils, the quantities of these nutrients in the top soil differed little between the treatments. After 3 years there were more deep burrowing earthworms (particularly Lumbricus terrestris) in tilled than in untilled soil.

Soil changes after 3-15 years of fertilized leguminous pastures on Tindall clay loam soil at Katherine, N.T. were studied by comparison of leguminous pasture soils with their native counterparts. Soil organic carbon, total nitrogen, C/N ratio and pH were unchanged by the presence of Townsville stylo (Stylosanthes humilis). Available phosphorus (bicarbonate extraction) was significantly higher under legume pasture, reflecting its fertilizer history, but there was no pattern of increase with time, nor with quantity of fertilizer. Available nitrogen (boiling water extraction) was higher under legume pasture, and both the absolute value under legume pasture and the change in amount were correlated significantly with the age of the pasture. Available nitrogen after three years of legume pasture was equal to that under unimproved pasture, suggesting that gains in this period merely balanced losses during clearing and establishment.

Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

A study was conducted at the Zonal Agricultural Research Station, UAS, GKVK, Bangalore in Alfisols during 2010 to know the effect of different organic mulches and in-situ green manuring on soil properties and weed dynamics in maize. The soil was red sandy loam, slightly acidic in pH and with low in available nitrogen and medium in available phosphorus and potassium. The experiment consists of nine treatments comprising different mulchels like straw, coir pith, coconut fronds, tank soil and in-situ green manuring of sunhemp and glyricidia as green leaf manuring and horse gram as intercrop and control which are replicated thrice in RCBD. The results indicated that the soil organic carbon content did not differ significantly due to different mulches and in-situ green manuring but differed significantly with respect to available nutrients and on weed dynamics. Among different treatments in-situ green manuring of sunhemp registered significantly higher available nitrogen (281.18 kg/ha) over other treatments but which was on par with green leaf manuring, horse gram intercropping and tank silt application. Similarly, in-situ green manuring of sunhemp recorded significantly higher available phosphorus (77.93 kg/ha) over application of additional FYM but was on par with other treatments. Mulching with coconut fronds (2.3 t/ ha) recorded higher available potassium (136.13 kg/ha) but which was on par with other mulches except mulching with straw, application of additional FYM and control. The population of total bacteria, fungi and P solublizers, Azotobactor were found be increased significantly after the harvest of the crop compared to the initial population, in-situ green manuring of sunhemp, green leaf manuring with glyricidia and intercropping of horse gram registered lower weed density of 24.41, 30.44 and 32.14 per m2 respectively over other treatments. Similar trend was noticed with respect to weed dry weight and weed control efficiency.

Soil fertility assessment is a key for sustainable planning of a particular area. Thus, the present study was conducted to assess the soil fertility status of the Regional Agricultural Research Station, Parwanipur, Bara, Nepal. The study area is situated at the latitude 27°4’40.9’’N and longitude 84°56’9.85”E at 75masl altitude. Altogether 76 soil samples were collected based on the variability of land at 0-20 cm depth. The texture, pH, OM, total N, available P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu and Mn content in the samples were determined following standard analytical methods. Arc-GIS 10.1 was used for soil fertility mapping. The soil structure was angular blocky, and varied between grayish brown (10YR 5/2) and dark grayish brown (10YR 4/2) in color. The sand, silt and clay content were 24.41±0.59%, 54.57±0.44% and 21.03±0.32%, respectively and categorized as silt loam and loam in texture. The soil was moderately acidic in pH (5.67±0.09), low in organic matter (0.74±0.04%) and available Sulphur (0.8± 0.1 ppm). The total nitrogen (0.06±0.001%), available boron (0.59±0.08ppm) and available zinc (0.51±0.05ppm) were low. Furthermore, available potassium (50.26±2.95ppm), available calcium (1674.6±46.3ppm) and available magnesium (175.43± 8.93ppm) were medium. Moreover, available copper (1.36±0.06 ppm) and available manganese (16.52±1.12 ppm) were high, while, available phosphorus (77.55±6.65 ppm) and available iron (85.88±7.05 ppm) were found high. It is expected that the present study would help to guide practices required for sustainable soil fertility management and developing future agricultural research strategy in the farm.

Abstract Experimental plots measuring 2 rows (30-inch row spacing) by 50 ft were planted on 12 May in a Waukegan silt loam soil at the University of Minnesota Agricultural Research Station, Rosemount. Treatments were arranged in a RCBD with 4 replications. Granular insecticides were applied with a modified Noble applicator at planting, either banded ahead of the press wheel or in furrow. Postemergence (25 Jun) sidedress applications of liquid insecticides were made with a CO2-powered backpack sprayer at 20 gpa. Percent lodging was determined on 16 Aug. On 25 Aug, 5 roots from each plot were dug, washed, and rated using the Iowa 1-6 scale (with half-point increments for higher sensitivity).
