Abstract

The study on nutrients requirement for degraded ravinous land was carried out during three consecutive years in pilot area of Model Watershed Jalaun, Bundelkhand, U.P. The main objective of this study was to workout the nutrients requirement of different crops on the basis of watershed technology. The different varieties of gram gave maximum yield at 20 kg N+60 kg P₂O₅/ha. Similarly, the different varieties of field pea's and cv.K75 of lentil also yielded highest grains at 20 kg N+60 kg P₂O₅/ha. Cultivar T 21 and UPAS 120 of arhar gave maximum yields at 60 kg P₂O₅/ha in association of recommended dose of nitrogen. Application of 60 kg P₂O₅/ha in association of recommended dose of nitrogen gave highest grain yield of urd by 10.43 q/ha. Gram, field pea's and wheat raised after soybean responded up to use of 25 kg N/ha, 25 kg N/ha and 160 kg N/ha, respectively. The different varieties of soybean gave maximum yield at 20 kg N+80 kg P₂O₅ + 40 kg K₂O/ha. Likewise, the different varieties of mustard gave maximum yield at 150 kg N/ha as compared to lower doses of nitrogen. Mustard gave maximum yield by 33.80 q/ha with the use of 40 kg S/ha in conjunction of 80 kg N + 40 kg P₂O₅ + 40 kg K₂0/ha. Varsha variety of jowar yielded maximum grains at 80 kg N/ha on the both class of land i.e,. II and III under rainfed situation. The direct seeded rice gave maximum yield of 29.50 q/ha at 80 kg N/ha in the catchments area of nala bund. Application of 50 per cent nitrogen through F.Y.M. in association of 50 per cent nitrogen through urea provided higher yields of sugarcane, urd and mustard over the 100 per cent recommended dose of N through both urea and F.Y.M. Therefore, on the basis of above results, farmers may be advocated for application of 25 to 35 per cent more nutrients especially NPK over their recommended doses for reaping the better yield from the reclaimed ravionous land.

Abstract

India recorded impressive achievement in agriculture since the onset of green revolution which enabled the country to overcome wide spread hunger, achieve self-sufficiency in food and bring economic transformation. The situation, however started turning adverse, with slow down in the growth rate of output due to decline in soil fertility. This situation can only improve with the help of integrated nutrient management (INM) based on soil test crop response (STCR) nutrient application in the soil, according to the soil formula so that we can get targeted yield of the crop and sustain the soil fertility. Holy Cross Krishi Vigyan Kendra has conducted experiments to assess the STCR to achieve target yield of wheat. On Farm Trials (OFT) were conducted on the farmers fields in 10 different locations. The soil is sandy loam in midland situation the soil reaction was acidic and low or medium in organic matter. The soil samples for soil fertility status were analyzed at initial and final stage of the crop with other agronomic parameters. The source of the technology was Jawaharlal Krishi Vishwavidyalay, Jabalpur (M.P). During Rabi season of 2011-12 and 2012-13 studies were conducted to find out the doses of fertilizer to obtain targeted yield economically. Three technical options adopted for the experimentation were: Farmers practice-35 q/ha, fertilizers dose were 80 kg, nitrogen, 60 kg phosphorus and 20 kg potash). Technical option 1-targeted yield 40 q/ha, fertilizers dose by STCR based were 90:55:69 and Technical option 2 -targeted yield 42 q/ha, fertilizer dose by STCR based were 107:63:75. The technical option 1 was the best to adopt as per the assessment and refinement.

Abstract

The experiments on farmers’ field were conducted at Krishi Vigyan Kendra, Indore in nearby two villages during 2016-17 to 2017-18 to assess the impact of soil and foliar application of potassium nutrition on productivity of soybean. On farm trial comprised of three treatments viz., T₁- farmer’s practice (18:45:0), T₂- recommended doses of potassium on soil test basis and T₃- foliar application of potassium (1%) were taken on the ten farmers field each year. The experimental design was Randomized Block Design with the ten replications in which farmers were taken as the replication. The result indicated that soybean grain yield in the soil application of recommended dose of potassium (T₂), was significantly superior over foliar application of the potassium (1%) (T₃) and farmer practices (T₁). The increase in yield was 18.97 per cent in the treatment T₂ and 12.20 per cent in treatment T₃ over the farmers’ practices (T₁). The soil application of recommended dose of potassium recorded significantly higher average pod per plant and seed index followed by the foliar application of potassium as compared to farmer practice (33.90). Similar trend were also recorded in the gross return, net return and B:C ratio.
