Abstract:
The present investigation was carried out to study the Influence of land configuration technique and soil amendments on nutrient uptake, soil amelioration and soybean yield in Vidarbha region of Maharashtra. The treatments comprised of only BBF, BBF + FYM @5 t ha-1, BBF + gypsum @ 2.5 t ha -1 and BBF + FYM @ 5 t ha-1 + gypsum @ 1.25 t ha -1 combinedly. Treatments replicated in six farmers’ fields one farmer as one replication with randomized block design. In this region poor drainage and sub soil Sodicity are the main problems. Salt affected soils limit crop yields around the world. Knowledge of how nutrient availability is affected in plants growing on salt affected soils is important in adopting appropriate management practices to satisfy plants’ nutritional requirements and improve yields. In the salt affected environment plants required to absorb essential nutrients from a dilute source in the presence of highly concentrated nonessential nutrients. Nutrient uptake and use efficiency in salt affected soils is low due to salt stress and negative interactions with cations and anions present in high concentrations. Hence, a higher amount of nutrients is necessary in salt affected soils compared to normal soils. Biological nitrogen fixation is also adversely affected in legumes grown on salt affected soils. Salts also reduce activity of many enzymes which supply energy for nutrient uptake. The important soils and plant management practices which can improve nutrient uptake and use efficiency in salt affected soils. in our experiment we have used soil amendments to reduce effect of salts, application of farmyard manures to create favorable plant growth environments, leaching salts from soil profile and provided favourable drainage facilities through BBF. Use of FYM and gypsum recorded considerable increase in soluble Ca, Mg and K but decrease in Na. In respect of bicarbonates the significant reduction was observed in treatment T3, BBF + gypsum@ 2.5tha-1. Concentration of chlorides and sulphates also reduced in T4 (1.06 (me L-1) due to combined application of FYM @ 5 t ha-1 and gypsum @ 1.25 t ha-1. InT3 also observed remarkable reduction over T1. The nutrient uptake was significantly higher in treatment (T4) in respect of nitrogen, phosphorus and potassium. 103.98 kg ha-1, 24.62 kg ha-1 and 69.53 kg ha-1 respectively. Treatment in which farm yard manure @ 5 t ha-1,and gypsum @1.25 t ha-1 were united in soil. This might be due to effective amelioration by organic and in organic amendments under BBF and same way supplying the nutrients in slight quantities to the plants. When the vicinity of plant roots is in good condition obviously plants perceives more nutrients.
