The present study was undertaken in the ongoing long-term experiment initiated during 2017 at experimental farm, College of Agriculture, Rajendranagar, Hyderabad. Soil samples collected from a depth of 0–15 cm was analysed for soil fertility parameters namely: available N, P and K. The results indicated that the different cropping systems had positive influence on improving the nutrient status (i.e., available N, P and K) significantly over the initial soil values (N: 112.20, P: 23.40 and K: 170.30 kg ha-1, respectively). 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. The maximum (221.60 and 221.57 kg ha-1) soil available nitrogen was obtained in Pigeon pea + Greengram (1:3) – Sesame after harvest of kharif and rabi, available phosphorus builds up was profound in Fodder maize – Lucerne (48.27 kg ha-1) and available K (207.63 kg ha-1) was higher in Rice –Maize cropping system after harvest. Fodder crops recorded significantly higher NPK uptake over other cropping systems.

The present study was undertaken in the ongoing long-term experiment initiated during 2017 at the experimental farm of College of Agriculture, Rajendranagar, Hyderabad. Soil samples were collected from two depths (0–15 and 15–30 cm) and analysed for soil fertility parameters namely: available N, P, K and S. The results indicated that the different cropping systems had positive influence on improving the nutrient status (i.e., available N, P and K) significantly over the initial soil values (N: 112.20, P: 23.40 and K: 170.30 kg ha-1, respectively). Interestingly, it was noticed that improved availability of nutrients (N, P, K and S) was more profound in the upper soil layer (0–15 cm) compared to lower depth (15–30 cm) in all the cropping systems (CS). The CS: Bt cotton + Greengram – Groundnut had recorded high nitrogen (N=221.60 kg-1), CS: Fodder maize – Lucerne recorded high in available P (P=49.13 kg-1) and CS: Fodder sorghum + Fodder cowpea – Horsegram – Sunhemp recorded high in K and S (K=208.10 kg-1, S= 172.0 kg S ha-1) after kharif season. While, CS: Pigeon pea + Greengram – Sesame showed high for N (N=228.57 kg-1), CS: Fodder maize – Lucerne for high P (P=48.27 kg-1) and Rice – Maize recorded high for K and S (K=207.63 kg-1 and S= 95.40 kg S ha-1) in top soil layer (0–15 cm) after harvest of rabi compared to lower soil depth (15–30 cm).

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.

Huge Impact

Availability of plant nutrients in rhizosphere is directly influenced by types of crop grown and land use pattern. The experiment was conducted in Diktel Rupakot Majhuwagadhi Municipality, Khotang, Nepal to assess the soil nutrients dynamics as influenced by different cropping system. Five different cropping systems (Rice – Wheat, Maize – Millet, Maize – Vegetables, Ginger and Cardamom) were selected as treatments and all treatments were replicated for five times for blocking in Randomized Complete Block Design. Soil samples from 0-15 cm depth were collected from each site and evaluated for soil pH, soil organic carbon (SOC), total nitrogen (N), available phosphorus (P), and available potassium (K). All the tested parameters except N were found to be significantly affected by cropping system. Soil in all five cropping systems were found acidic (pH<6.5) in nature with pH ranging from 5.180-6.640. The SOC was recorded highest (3.102%) from Cardamom based system and lowest amount of SOC was observed in Ginger based system. The highest amount of P (32.14 mg/kg) was reported in Maize – Vegetables cropping system and lowest P content (5.72 mg/kg) was recorded from Cardamom based system. P content in Ginger based system (31.51 mg/kg) was statistically at par with that of Rice – Wheat system. The highest K content (306.50 mg/kg) was recorded from Maize – Vegetable cropping system and lowest K content (34.80 mg/kg) was observed in Cardamom based system which is statistically similar to Rice –Wheat (35.70 mg/kg) and Maize –Millet systems (77.20 mg/kg). The result indicated that cropping systems have huge impact on plant nutrient dynamics in soil. Int. J. Appl. Sci. Biotechnol. Vol 7(3): 341-346

A field experiment was conducted during 2016-17 at AICRP on Integrated Farming Systems, Regional Sugarcane and Rice Research Station, Rudrur to diversify existing rice-rice cropping system with less water requiring crops under irrigated dry conditions for vertisols of Northern Telangana Zone. The experiment was laid out with twelve cropping systems as treatments in Randomized Block Design (RBD) with three replications. The twelve combinations of cropping systems tested during kharif and rabi seasons were rice – rice (check), maize + soybean (2:4) – tomato, maize + soybean (2:4) - rice, maize - sunflower + chickpea (2:4), maize - chickpea, Bt cotton + soybean (1:2) on broadbed – sesame + groundnut (2:4), Bt cotton - sesame + blackgram (2:4), soybean – wheat, soybean – sunflower + chickpea (2:4), turmeric – sesame, turmeric + soybean (1:2) on flat bed – bajra and turmeric + soybean (1:2) on broadbed – sesame + blackgram (2:4). On system basis, significantly higher productivity in terms of rice equivalent yield (REY) of 23830 kg ha-1 was recorded with turmeric+soybean (1:2) BBF– sesame+blackgram (2:4) turmeric – sesame cropping sequence. However it was on par with turmeric – sesame and turmeric + soybean (1:2) on flat bed – bajra crop sequence with productivity of 23332 kg ha-1 and 21389 kg ha-1 respectively. Lower productivity was recorded with rice-rice cropping system (10725 kg ha-1). Significantly higher system net returns were recorded with Bt. cotton – sesame + black gram (2:4) on BBF (Rs222838 ha-1) closely followed by Bt Cotton + Soybean (1:2) (BBF) - Sesamum + Groundnut (2:4) (Rs221160 ha-1) and Maize+soybean (2:4)–tomato (Rs212909 ha-1). Lower system net returns were recorded in conventional rice-rice system (Rs88179 ha-1). Bt. cotton – sesame + black gram (2:4) and Bt Cotton + Soybean (1:2) (BBF)- Sesamum + Groundnut ((2:4) and Maize+soybean (2:4)–tomato were economically superior with REE of 152.71%, 150.81% and 141.45%. Rice- Rice cropping adopted by majority of farmers is less productive and economically inferior indicating wider scope of diversifying existing rice- rice cropping system with high productive, economically viable cropping systems in vertisols of Northern Telangana Zone.
