Effect of contour rainwater-harvesting and integrated nutrient management on sorghum grain yield in semi-arid farming environments of Zimbabwe

A field experiment was carried out during summer season of 2018 at Instructional Farm, Jaguli, BCKV, West Bengal to study the effect of integrated nutrient management on growth, yield and economics in hybrid maize. The treatments were T1-100% RDF (150:75:75 kg/ha N, P2O5 and K2O) (control), T2- 75% RDF+ Vermicompost @ 2t/ha, T3-75% RDF+ Yeast Vinasse @ 2t/ha, T4-75% RDF+ Vermicompost @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T5-75% RDF+ Yeast Vinasse @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T6-75% RDF+ Vermicompost @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% and T7-75% RDF+ Yeast Vinasse @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% replicated thrice in RBD. The result of the experiment revealed that application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 (T6) exhibited maximum plant height (250.97 cm), LAI (4.58), dry matter accumulation (1680.38 g/m2), number of grains/cob (402.64), cob length (22.34 cm), grain yield (9.04 t/ha), stover yield (13.50 t/ha), net return (Rs.77112/ha), BCR (2.33) and uptake of N, P2O5 and K2O (200.54, 66.45 and 119.12 kg/ha respectively) over application of 100% RDF. However, T6 was statistically at par with the T4 and T7, which produced 8.94 and 8.75 t/ha grains respectively. Therefore, the study concluded that integrated application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 can be recommended for better grain yield and higher profit of summer maize.

Boro Rice

For sustainable boro rice production in Bangladesh, a balanced fertilization to improve the current soil condition caused by mono-application of inorganic fertilizers and appropriate rice variety selection are very crucial. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the boro season of December 2016 to May 2017 to evaluate the effect of integrated nutrient management on two boro rice cultivars. The varieties were BRRI dhan28 and BRRI dhan29 and eight kinds of nutrient management viz., control (no fertilizers), recommended dose of inorganic fertilizers (120-60-40 N, P2O5, K2O kg ha-1 + gypsum 60 kg ha-1 and ZnSO4 @ 10 kg ha-1), full dose of poultry manure @ 5 t ha-1, cowdung @ 10 t ha-1, poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of other inorganic fertilizers, cowdung @ 5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers, poultry manure @ 2.5 t ha-1 + 75% prilled urea and full dose of inorganic fertilizers, and cowdung @ 5 t ha-1 + 75% prilled urea and full dose of other inorganic fertilizers. The experiment was laid out in a split plot design with three replications. Result showed that, yield and yield components of boro rice were significantly influenced by variety, nutrient management and interaction of variety and nutrient management. In respect of grain yield, BRRI dhan29 produced the maximum yield (5.46 t ha-1). BRRI dhan28 showed poor performance with all characters and gave the minimum yield (4.07 t ha-1). In case of nutrient managements, the highest yield and yield component were obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers and produced the maximum grain yield (5.70 t ha-1). In the interaction of variety and integrated nutrient management, the highest grain yield (6.83 t ha-1) and straw yield (7.61 t ha-1) was obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers with BRRI dhan29 variety. So, BRRI dhan29 with 2.5 t ha-1 poultry manure + 50% prilled urea and full dose of the recommended inorganic fertilizers might be a promising practice for boro rice cultivation.

Pooled Data

A field experiment was conducted in Vertisols at Bijapur during 1994-96 to study the effect of tillage practices and integrated nutrient management on winter sorghum yield and soil nutrient availability. The increase in winter sorghum yield with deep tillage over medium and shallow tillage was 27 and 57% in 1994-95 as compared to 18 and 34% in 1995-96. Deep tillage resulted in 22 and 45% higher yield as compared to medium and shallow tillage in the pooled data. This was mainly due to conservation and increased availability of moisture and nutrients, i.e. N, P and K. The higher availability of nutrients in the topsoil (0-0.15 m) as compared to the subsoil (0.15-0.30 m) was due to the application of nutrients in the topsoil layer and the higher rate of mineralization. Among the organic materials applied, Leucaena loppings at 2.5 t ha-1 led to a significantly (9%) higher yield (1636 kg ha-1) over vermicompost (1500 kg ha-1) and was on par with farmyard manure (1572 kg ha-1) in the pooled data and during both years of the study. The higher percentage increase in grain yield with Leucaena application was due to the better moisture conservation and availability of major nutrients, i.e. N, P and K. Winter sorghum responded significantly to N application at 25 kg ha-1 in 1994-95, whereas in 1995-96 and in the pooled data the response varied up to 50 kg N ha-1. In the pooled data, the grain yield increased by 17 and 24% with the application of 25 and 50 kg N ha-1 compared with the control. The higher yields obtained with the application of nitrogen were due to the better availability of nutrients, especially N, as these soils are low in available N.

An experiment was conducted to study the effect of integrated nutrient management in scented rice and its residual effect on pea under paira cropping system at Regional Research and Technology Transfer Station (RRTTS), Bhawanipatna, Kalahandi, Odisha during 2015-16 and 2016-17. Twelve treatment combinations comprising of T1 - FYM @ 10 t ha-1 + vermicompost @ 2.5 t ha-1 + neem cake @ 2.5 q ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T2 - STBFR (Soil test based fertilizer recommendation 75 : 30 : 20 kg N:P2O5: K2O ha-1), T3 - STBFR + FYM @ 5 t ha-1, T4 - STBFR + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T5 - STBFR + Zn @ 5 kg ha-1, T6- STBFR + S @ 20 kg ha-1, T7- STBFR + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T8- STBFR + FYM @ 5 t /ha + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T9 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T10 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5kg ha-1+ PSM @ 5kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T11 - Farmers practice (only chemical fertilizer @ 40 : 20 : 20 kg N : P2O5 : K2O ha-1), T12 - STBFR + vermicompost @ 2.5 t ha-1 were tried in RBD with three replications. The soil of the experimental site was black cotton type having pH- 6.11 , O.C.- 0.72 %, E.C- 0.004 (dS m-1), available N -175.9 kg ha-1 (low), available P-36.7 kg ha-1 (medium) and available K- 283.6 kg ha-1 (high). Geetanjali was the test variety for rice and Azad Pea-1 for pea. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) to medium duration aromatic rice (var. Geetanjali) produced higher rice grain yield (4065 kg ha-1) and pea seed yield (1044 kg ha-1) from aromatic rice -pea paira cropping system. However, application of STBFR + FYM @ 5 t ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 producing grain yield (3944 kg ha-1) and pea seed yield 977 kg ha-1 is another option. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) recorded maximum gross return (Rs. 1,26,991 ha-1) , net return (Rs. 80,146 ha-1) and B : C ratio of 2.71. The increase in rice equivalent yield (REY) in this treatment was 51.4% higher than the farmer practice i,e., application of chemical fertilizers alone (40 : 20 : 20 kg N : P2O5 : K2O ha-1).

Partial Factor

SUMMARYIn the Sahelian zone of Niger, there is a need to develop guidelines for integrated nutrient management, which relies on the potential nutrient sources of manure, pearl millet residue and mineral fertilizers. A fully factorial on-station experiment was conducted during the 1994 and 1995 rainy seasons at Sadoré, Niger, combining application of: (i) broadcast millet residue (300, 900 and 2700 kg ha−1), (ii) broadcast cattle manure (300, 900 and 2700 kg ha−1) and (iii) mineral fertilizer (unfertilized control, 15 kg N ha−1 + 4.4 kg P ha−1 and 45 kg N ha−1 + 13.1 kg P ha−1). Manure and fertilizer increased millet yields in both years whereas residue was effective in 1995 only. The effect of manure and residue were additive, as was the effect of manure and fertilizer but only up to 50 kg N ha−1. However in 1995, the response to fertilizer was approximately doubled in the presence of 900 or 2700 kg residue ha−1 compared to fertilizer with 300 kg ha−1 residue, indicating a strong synergistic effect. This synergistic effect was reflected in the partial factor productivity of nitrogen and phosphorous in both years. Two treatment combinations stand out as particularly relevant based on yield, partial factor productivity and nutrient balance criteria: 2700 kg manure ha−1 combined with (i) 300 kg residue and no fertilizer (95% grain yield increase); (ii) 900 kg residue ha−1 and 15 kg N + 4 kg P ha−1 (132% grain yield increase). There is a need for similar, long-term experiments to confirm the present results.

The Impact

Over years of intensive cultivation and imbalanced fertilizer use, the soils of the Indiansubcontinent have become deficient in several nutrients and are impoverished in organic matter.Recently, this region has started emphasizing a shift from inorganic to organic farming to managesoil health. However, owing to the steadily increasing demands for food by the overgrowingpopulations of this region, a complete shift to an organic farming system is not possible. The rice–wheat cropping system (RWCS) is in crisis because of falling or static yields. The nations of thisregion have already recognized this problem and have modified farming systems towardintegrated nutrient management (INM) practices. The INM concept aims to design farmingsystems to ensure sustainability by improving soil health, while securing food for the populationby improving crop productivity. Therefore, this paper was synthesized to quantify the impact androle of INM in improving crop productivity and sustainability of the RWCS in the context of theIndian subcontinent through meta-analysis using 338 paired data during the period of 1989–2016.The meta-analysis of the whole data for rice and wheat showed a positive increase in the grainyield of both crops with the use of INM over inorganic fertilizers only (IORA), organic fertilizersonly (ORA), and control (no fertilizers; CO) treatments. The increase in grain yield was significantat p < 0.05 for rice in INM over ORA and CO treatments. For wheat, the increase in grain yield wassignificant at p < 0.05 in INM over IORA, ORA, and CO treatments. The yield differences in theINM treatment over IORA were 0.05 and 0.13 Mg ha−1, respectively, in rice and wheat crops. Thepercent yield increases in INM treatment over IORA, ORA, and CO treatments were 2.52, 29.2, and90.9, respectively, in loamy soil and 0.60, 24.9, and 93.7, respectively, in clayey soil. The net returnsincreased by 121% (INM vs. CO) in rice, and 9.34% (INM vs. IORA) and 127% (INM vs. CO) inwheat crop. Use of integrated nutrient management had a positive effect on soil properties ascompared to other nutrient management options. Overall, the yield gain and maintenance of soilhealth due to INM practices over other nutrient management practices in RWCS can be a viablenutrient management option in the Indian subcontinent.
