“…The highest microbial population was recorded in T 5 treatment because it was supplemented with a maximum dry matter of tomato (19.95 t ha −1 ) in the field coupled with farmyard manure (@ 10.0 t ha −1 ) that provided an adequate amount of food to the microorganisms, which proliferated efficiently in the soil under ambient conditions in the mulched plots. Previous studies 42 , 43 also reported higher microbial masses of bacteria, fungi, and actinomycetes in the plots that received farmyard manure integrated with solid fertilizers and green manures. The use of liquid fertilizers integrated with farmyard manure also helped improve the microbial population due to soil conditioning with the organic source.…”

India produces around 19.0 million tonnes of tomatoes annually, which is insufficient to meet the ever-increasing demand. A big gap of tomato productivity (72.14 t ha–1) between India (24.66 t ha–1) and the USA (96.8 t ha–1) exist, which can be bridged by integrating trellis system of shoot training, shoot pruning, liquid fertilizers, farmyard manure, and mulching technologies. Therefore, the present experiment was conducted on tomato (cv. Himsona) during 2019–2020 at farmers' fields to improve tomato productivity and quality. There were five treatments laid in a randomized block design (RBD) with three replications; T1 [Farmer practice on the flatbed with RDF @ N120:P60:K60 + FYM @6.0 t ha−1 without mulch], T2 [T1 + Polythene mulch (50 microns)], T3 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 8.0 t ha−1 + Single shoot trellis system + Side shoot pruning + Liquid Fertilizer (LF1—N19:P19:K19) @ 2.0 g l–1 for vegetative growth + Liquid Fertilizer (LF2—N0: P52: K34) @ 1.5 g l–1 for improving fruit quality], T4 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 8.0 t ha−1 + Single shoot trellis system + Side shoot pruning + LF1 @ 4.0 g l–1 + LF2 @ 3.0 g l–1], and T5 [Tomato plants grown on the raised bed with polythene mulch + FYM @ 10.0 t ha−1 + Single shoot trellis system + Side shoot pruning + LF1 @ 6.0 g l–1 + LF2 @ 4.5 g l–1]. The results revealed that tomato plant grown on the raised beds with polythene mulch, shoot pruning, trellising, liquid fertilizers, and farmyard manure (i.e., T5) recorded higher shoot length, dry matter content, and tomato productivity by 20.75–141.21, 18.79–169.4, and 18.89–160.87% as compared to T4–T1 treatments, respectively. The T5 treatment also recorded the highest water productivity (28.39 kg m–3), improved fruit qualities, net return (10,751 USD ha–1), benefit–cost ratio (3.08), microbial population, and enzymatic activities as compared to other treatments. The ranking and hierarchical clustering of treatments confirmed the superiority of the T5 treatment over all other treatments.

A field experiment entitled “Effect of inorganic fertilizers in combination with biofertilizers on nutrient content and uptake of kharif maize” was conducted at Agriculture College Farm, Bapatla, during both kharif 2020 and 2021. The experiment was laid out in randomized block design (RBD) with seven treatments and replicated thrice. The treatments consisted of T1- Control; T2- 100% RDF; T3- 125% RDF; T4 – 100% RDF + VAM; T5- 100% RDF +VAM + Azospirillum + PSB; T6- 75 % RDF + VAM; T7- 75 % RDF + VAM + Azospirillum + PSB. During kharif in two years of study significantly higher nitrogen content and uptake was recorded with 125 % RDF (T3) it was on par with 100% RDF + VAM + Azospirillum + PSB (T5) and 100% RDF + VAM (T4). The maximum nitrogen content and uptake was significantly influenced due to various level of inorganic fertilizers. Higher phosphorus, potassium and sulphur (non-significant) content and uptake were recorded in the treatment T5 that received 100% RDF +VAM + Azospirillum + PSB and it was on par with treatment which received 75 % RDF + VAM + Azospirillum + PSB (T7), 125 % RDF (T3) and 100% RDF + VAM (T4) at knee high, tasseling and harvest stage of maize. The results revealed that application of biofertilizers along with inorganic fertilizers significantly increased plant nutrient content and uptake of maize crop.

The article presents data on the change in the enzymatic activity of the soil in winter wheat crops under the influence of the methods and techniques of tillage and the previous crop in the Central Ciscaucasus zone. The studies were carried out in the zone of the Central Ciscaucasia on the basis of the experimental station of Stavropol State Agrarian University. The determination of the activity of invertase shows that its maximum values are in the variants of the combined treatment, which is associated with more favorable hydrothermal conditions of the arable layer of the soil. Thus, according to its predecessor, pea + oats for green fodder, invertase activity is 27.9 mg of glucose per 1 g of soil for 40 hours, which is almost twice as high in comparison with surface treatment and three times with plowing. The decrease in the activity of invertase during dump processing indicates a rapid rate of mineralization of organic matter. Catalase activity on the studied precursors: on peas with oats for green fodder 1.6 and 1.3; 1.5 and 1.8 peas; for corn silage 1.5 and 1.4 ml 0.1 n. KMnO4 per 1 g of soil for 20 minutes. Revealed a decrease in activity under the influence of plowing, as urease enters the soil with plant debris. When dumping treatment due to movement of plant residues in the underlying layers, the activity of this enzyme decreases to 0.8–0.9 mg of N-NH4 per 10 g of soil for 4 hours, whereas with surface treatment, depending on its predecessor, it is 0.8–– 1.3 mg of N-NH4 / 10 g of soil for 4 hours, with a combination of 1.0–1.1, and for shallow soil, 1.1–1.2 mg of N-NH4 / 10 g of soil in 4 hours.
