A field study was conducted to analyze the effect of long term use of organic and inorganic fertilizers on productivity and soil fertility under paddy-sesame cropping system. Application of 100% NPK + secondary and micro-nutrients based on soil test (T7) showed significantly higher mean grain yield of paddy (4735 kg/ha) and sesame (460 kg/ha) and rice equivalent yield (5348 kg/ha) followed by application of 50% NPK + 50% N as Farmyard manure (FYM) + inorganic source of micronutrients as per soil test (T1). Whereas, application of 50% recommended dose of nitrogen (RDN) through FYM + bio-fertilizers for N + Recommended dose of phosphorus (RDP) through rock phosphate + phosphorus solubalizing bacteria (PSB) showed significantly least mean grain yield of paddy (3209 kg/ha) and sesame (314 kg/ha) and rice equivalent yield (3628 kg/ha). Further, among organic treatments (T2 to T6), higher mean grain yield of paddy (3834 kg/ha), sesame (326 kg/ha) and rice equivalent yield (4269 kg/ha) as compared to other treatments was recorded following the application of one third of RDN through FYM + one third of RDN through vermicompost + one third of RDN through neem cake + bio-fertilizers containing N and P carriers (T6). Whereas, higher nutrient status with respect to major and micronutrients and the improved soil fertility status was recorded in organic treatment plots. The application of nutrients through organic sources would improve the soil fertility status under paddy-sesame cropping system.

An Randamised Block Design (RBD) field investigation with ten crop sequences under irrigation with recommended package of practices in sandy loam soils of Southern Telangana Zone (STZ), Telangana was carried out during Kharif, Rabi and summer of 2018-2019 with an objective of the nutrient uptake and soil fertility status under different cropping systems and to assess agro economic benefit. These ten cropping systems were grouped in to five categories viz., pre dominant cropping systems of the zone, ecological cropping systems, household nutritional security giving cropping systems, fodder security giving cropping systems and cropping systems involving high value crops. So that from each category, best cropping system can be identified and can be suggested to different integrated farming systems models. In the context of farming systems, under high value crops such as Okra–Marigold–Beetroot system recorded significantly higher rice grain equivalent yield (36,434 kg ha-1) over other systems. Among the ecological cropping systems for improving soil health, Bt cotton + green gram (1:3) - groundnut cropping system was recorded significantly higher rice grain equivalent yield (14,080 kg ha-1) as  compared to pigeon pea + green gram (1:7) – sesame cropping system. Among the household nutritional security giving crops, pigeon pea + maize (1:3) – groundnut system was recorded higher rice grain equivalent yield (13,693 kg ha-1). Within the two fodder crops, fodder maize – lucerne system was resulted in higher rice grain equivalent yield (7,709 kg ha-1). Rice - maize and Bt cotton which were the pre-dominant cropping systems of the region wherein rice – maize system recorded comparatively higher rice grain equivalent yield (11,771 kg ha-1) than Bt cotton. Fodder systems were found to be more exhaustive than all other cropping systems. However, within two years of experimentation the changes in physic-chemical properties and soil fertility status were not significantly affected except organic carbon. Organic carbon was high (0.45 %) in case of pigeon pea + green gram (1:6) - sesame cropping system.

Soil Fertility Status

Soil fertility assessment is a very fundamental task for farmers and agricultural planners to adopt appropriate fertility management practices, to recommend applying lacking fertilizers, to make fertility-based agricultural plans,s and to produce a large number of crops in their land. This study assesses the soil fertility status of Sainamaina Municipality, ward no. 5-9, Rupandehi district based on soil sample data collected from the field. Soil test based fertility assessment, calculation of overall fertility of area using fertility index, and preparation of soil fertility map is carried out. As soil fertility, the status of total nitrogen (TN), phosphorus (P2 O5), potassium (K), organic matter (OM), and soil pH are measured. As a result, the status of TN, (K2 O), and OM is found low, the status of (P2 O5 ) is found high and soil pH is found in range of very strongly acidic to slightly alkaline.

The Impact

The field experiments was conducted is an ongoing All India Co-ordinate Research Project on “Long term Fertilizer Experiment” during 2018-2019 with soybean-wheat cropping sequence at the Research Farm Department of Soil Science, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.), India. The objective of the study was the Impact of long term application of inorganic fertilizers and organic manure on soil fertility and crop productivity under soybean-wheat cropping system in a Vertisol. The experiment consists of ten treatments i.e. T1 50% NPK, T2 100% NPK, T3 150% NPK, T4 100% NPK + Hand Weeding, T5 100% NPK + Zn, T6 100% NP, T7 100% N, T8 100% NPK+ Farm Yard Manure, T9 100% NPK–S and T10 unfertilized plot (control) with four replications in a randomized block design. The findings of the present study indicated that the soil pH and EC were remaining unaltered even after continuous application of variable amounts of fertilizers either alone or in combination. A significant positive change in soil organic carbon, available N P K and S content was observed with continuous additions of balanced fertilizers and manures over the imbalanced or unfertilized treatments. The findings showed that the application of recommended dose of N, P and K (20:80:20 kg ha-1 for soybean and 120:80:40 kg ha-1 for wheat) with organic manure (FYM) @ 5 t ha-1 resulted in 185.8% and 325.9% increase over control in soybean and wheat yields, respectively. Thus, the continuous use of balanced fertilization, either alone or in combination with organic manure is necessary for sustaining soil fertility and productivity of crops.

Soil Fertility Status

The conversion of organic wastes into biochar via the pyrolysis technique could be used to produce soil amendments useful as a source of plant nutrients. In this study, we investigated the effects of fruit peels and milk tea waste-derived biochars on wheat growth, yield, root traits, soil enzyme activities and nutrient status. Eight amendment treatments were tested: no amendment (CK), chemical fertilizer (CF), banana peel biochar 1% (BB1 + CF), banana peel biochar 2% (BB2 + CF), orange peel biochar 1% (OB1 + CF), orange peel biochar 2% (OB2 + CF), milk tea waste biochar 1% (TB1 + CF) and milk tea waste biochar 2% (TB2 + CF). The results indicated that chlorophyll values, plant height, grain yield, dry weight of shoot and root were significantly (p < 0.05) increased for the TB2 + CF treatment as compared to other treatments. Similarly, higher contents of nutrients in grains, shoots and roots were observed for TB2 + CF: N (61.3, 23.3 and 7.6 g kg−1), P (9.2, 10.4 and 8.3 g kg−1) and K (9.1, 34.8 and 4.4 g kg−1). Compared to CK, the total root length (41.1%), surface area (56.5%), root volume (54.2%) and diameter (78.4%) were the greatest for TB2 + CF, followed by BB2 + CF, OB2 + CF, TB1 + CF, BB1 + CF, OB1 + CF and CF, respectively. However, BB + CF and OB + CF treatments increased β-glucosidase and dehydrogenase, but not urease activity, as compared to the TB + CF amendment, while all enzyme activity decreased with the increased biochar levels. We concluded that the conversion of fruit peels and milk tea waste into biochar products contribute the benefits of environmental and economic issues, and should be tested as soil amendments combined with chemical fertilizers for the improvement of wheat growth and grain yield as well as soil fertility status under field conditions.
