In the spring-summer agricultural cycle of 2016, the hybrids P4082W, H565, and DK357 were evaluated with chemical and chemical + biological fertilization by means of a factorial experiment arranged in a split-plot design. In the treatments with biofertilizer the seed was inoculated with Glomus intraradices + Azospirillum brasilense; in chemical fertilization 120N-80P-80K was applied. The response variables measured were: height, diameter of the neck and number of leaves of the plant, number and weight of ears with and without bracts, weight of bracts, length and diameter of the ear, number of rows ear-1, grain weight of 5 ears of cobs, length, diameter and weight of the cobs, grain yield, fodder and dried grinding. To determine the profitability of the systems, the total cost (TC), total income (IT), and net income (IN) were calculated, and finally the gain by invested MXN peso (GIP). The statistical analysis included analysis of variance and test of comparisons of means by the Tukey method. It was found that the hybrid DK357 recorded the highest height, number of leaves, grain weight, length of ear and cob, yield of grain and forage, both “zacateado” and dried milled. The P4082W genotype obtained the highest weight of ear with and without bracts. The chemical fertilization favored the yield of forage zacateado, and in combination with the biological treatment, increased the yield of grain. The DK357 and P4082W hybrids grown with chemical and biological fertilization turned out to be profitable in the systems for the production of grain alone, forage grass and grain, and ground dried fodder.

ABSTRACT The intensive cultivation of vegetables with frequent chemical fertilization may cause accumulation of nutrients in the soil. This, in turn, may reduce crop yields and damage the environment due to contamination of ground water and rivers. Thus, to increase the effects of P (0, 100, 200, 300 and 400 kg ha -1 of P2O5) and K (0, 60, 120, 180 and 240 kg ha-1 of K2O) doses on the growth and productivity of radish cultivars (Sakata 19 and Sakata 25) in a soil with high levels of these nutrients, two experiments were conducted in randomized blocks with the factors cultivars and doses arranged in a 2 x 5 factorial design with three replications. Number of leaves per plant, leaf area, shoot and root dry mass, total and commercial productivity, percentage of cracked roots and P and K contents in the plant and in the soil were evaluated. The Sakata 19 cultivar performed better than the Sakata 25 in both experiments. The fertilization with P or K did not influence the growth and the productivity of both radish cultivars. Therefore, both cultivars of radish evaluated do not need to be fertilized with P and K when planted in a Latosol with high levels of these nutrients.

A field experiment was conducted at National Citrus Research Program (NCRP), Paripatle, Dhankuta to standardize the time and method of grafting and to assess the success and growth of mandarin saplings. Scions taken from ‘Khoku Local’ mandarin were grafted onto one-year-old trifoliate orange seedling rootstocks by shoot tip and veneer methods in eight different dates starting from 29th October, 2009 to 12th February, 2010 at 15 days interval. The grafts were planted inside closed tunnel of jute and plastic sheet at 10×10 cm spacing in 50×60 cm2 experimental plots in two factorial split-plot design with three replications per treatment, containing 30 grafts per plot. The grafting methods were allotted on main-plots and the dates on sub-plots randomly. The success and growth of sapling was significantly affected by the dates while the methods had no effect. Study results showed that the highest success (96.11 %) was found on 13th January, followed by 28th January (91.11%) and the least (51.67%) on 29th October grafting. The mortality of sprouted grafts was the lowest (0.17%) in 29th December grafting, while it was observed higher in earlier and late season grafting. Observation on growth taken at 180 days after grafting in successful grafts showed that 29th October had the highest number of primary branches (2.2); 14th November had the highest number of leaves (48.47) and secondary branches (2.505); 29th December gave the maximum sapling height (32.86 cm); 13th January produced the lowest number of leaves (21.93) per sapling and 28th January produced the lowest number of primary (1.533) and secondary branches (1.172) per sapling. From the study it was revealed that in Dhankuta, the most appropriate time of grafting was 2nd to 4th week of January.

ABSTRACT High corn yields in high-tech systems are related to proper crop implementation. This study aimed to evaluate the effects of variability in the distribution of seeds along the planting row on corn production components. The study was conducted under Cerrado conditions in the municipality of Urutaí, GO, Brazil. The experimental design was randomized blocks in a 5 x 2 factorial scheme, with four replicates. The effects of five coefficients of variation (0, 20, 40, 60 and 80%) of non-uniformity in the spatial distribution of seeds along the planting row of two corn hybrids (P30F53HX and P3646HX) were evaluated. No interactions were observed for the analysed corn variables. However, as the non-uniformity in seed distribution along the planting row increased, stalk diameter, hundred-grain weight, number of rows per ear, number of kernels per row and ear length decreased. Additionally, linear reductions were observed in corn grain yield with the increase in the coefficient of variation of the spatial distribution of seeds along the planting row. Between the hybrids, the 30F53HX showed higher hundred-grain weight.

In the conditions of the south of the Nonchernozem Zone, intraspecific hybridization of winter soft wheat was carried out. When selecting parental forms used in crossing, special attention was paid to such economically valuable traits as productive tilling capacity, the number of grains and the mass of grain per spike. The true (Htru) and hypothetical heterosis (Hhyp) on the basis of “plant height”, “length of the lower internode”, “length of the upper internode”, “general tilling capacity”, “productive tilling capacity”, “spike length”, “number of spikelets”, “number of grains” and “grain weight per spike” were determined. It was established that the inheritance of quantitative traits in hybrids of the first generation was distinguished by the complex nature of distribution by types. Studies have made possible to identify 5 hybrid combinations F1, in which the effect of heterosis manifests itself simultaneously on five quantitative characteristics (ear length, number of spikelets per ear, number of grains per ear, grain weight per ear, mass grain from a plant).

The productivity of organic farming has mainly focused on its relative crop yields than the proportions of organic matters in soil. However, organically cultivation changes crop yields at the same time it depends on types of crops grown. Here, we provide a pot experiment on the rooftop in Latin Square Designs (LSD) with a Diamant variety of potato and four treatment combinations to evaluate variety’s growth and yields. T0: Control, T1: 100% organic fertilizer, T2: 75% organic fertilizer+25% soil and T3: 50% organic fertilizer+50% soil was used for the present study with three replications. Our analysis showed the tallest (23.78 cm) plant was in T2 followed by T1 and T3 (23.37 cm and 23.14 cm, respectively). T2 produced the maximal (76.44) number of leaves per stem followed by T2 and T3 (73.44 and 74.11, respectively). T1 generating the maximal number (6.89) of tubers per hill was significant than all the other treatments. The highest weight (19.13 gm) per tuber per hill was examined in T2 followed by T1 and T3 (17.05 gm and 12.91 gm, respectively). T2 produced the utmost tuber length (3.78 cm) followed by T1 and T3 (3.39 cm and 3.23 cm, respectively. 75% organic fertilizer+25% soil has concluded the potential to be grown successfully and the most suited treatment for production of potato (Diamant) in coastal areas of Bangladesh.

An increase in spring barley acreage requires a detailed study of the interaction of agronomic and climatic factors, as well as the selection of a modern set of new varieties. The use of mineral fertilizers is one of the most important methods to improve the productivity of grain crops and maintain a deficit-free balance of mineral nutrients in arable soils. The current study of the effective use of various doses of mineral fertilizers (NPK) on the new spring barley variety ‘Znatny’ was carried out on dark-gray forest heavy loamy soil in 2018–2020 by the Institute of Seed production and Agrotechnologies, a branch of the Federal Budgetary Scientific Institution “Federal Research Agro-Engineering Center VIM”. There has been established that the date of the phenological phases and the length of interphase periods did not depend on fertilizer rates, but had a close correlation with weather conditions (r = +0.68). The analysis of the obtained data has shown that an increase in the rates of applied fertilizers increases the aboveground biomass, which, in turn, negatively affects productivity of the barley variety ‘Znatny’ (r = -0.77). The analysis of the yield structure and rates of fertilizers NPK has shown that in the trial, the spring barley productivity was influenced by 1000-grain weight (r = +0.60). There was found a high inverse correlation between productivity and length of head (r = -0.85). When length of head ranged from 7.5 to 8.4 cm, grain weight per head remained practically at the same level in all variants (1.1–1.2). This indicated that at a rate of N90P90K90 and N120P120K120, the variety ‘Znatny’ formed a not very dense head. Protein percentage at these rates also greatly reduced. According to the obtained data, an increase in the doses of applied fertilizers (N90Р90К90–N120Р120К120) resulted in the intensified development of most leaf diseases and a decrease in lodging resistance. Thus, the optimal dose of application of azophoska fertilizer on dark-gray forest soil is the norm N45P45K45, since on this option there was obtained maximum productivity and net income. the increase in the recom[1]mended norms of mineral fertilizers, sharply reduces profitability of crop cultivation.

Melon are one of the most popular fruit commodities, but, despite the demand, its production in Indonesia has declined. One measure that can be used to optimize the quality of melon fruit is to trim off the leaf buds and arrange the position of fruiting on the stem, and this study, using the golden melon cultivar ‘Apollo,’ aimed to identify the effects of leaf bud trimming and fruit position arrangement in improving the quantity and quality of the fruit harvest. The experiment was conducted from March to May 2018 in the greenhouse of Food Crop and Horticulture Agribusiness Development (UPT Pengembangan Agribisnis Tanaman Pangan dan Hortikultura), in Lebo, Sidoarjo, Indonesia. It was based on a split-plot design, with leaf bud trimming as the main factor, consisting of two groups (trimming or not trimming), and fruit positions as the secondary factor, consisting of four stages, all repeated at four different time intervals. A correlation was found between leaf bud trimming and fruit position arrangement toward the number of leaves. However, the treatments did not affect the growth and yield of the plants, but did have a significant effect on fruit weight, sweetness, and volume. It was concluded that trimming off the leaf buds and arranging the fruiting position on golden melon plants can increase the quality of fruits, with the treatment involving trimming combined with arranging fruiting on the twelfth–thirteenth segment showing the best results.

The objective of this work was to study the effect of strawberry cultivar Douglas A split-plot design with four replicates was adopted. The results indicated a substantial increase in the content of the available macro and micro nutrients in the fumigated soils compared to the non fumigated ones. A significant increase in the number of leaves per plant, fresh and dry weight, early and total yield per plant was recorded. Fumigation accompanied by fertilization increased the available content (N,P and K and (Fe, Mn, Zn, and Cu) in the soil in the both growing seasons compared to fumigated only or the control. Plants grown in the fumigated fertilized plots contained the highest amount of macro and macro nutrients in both the growing seasons. Fumigated non fertilized plots had the highest amount of available P and K than all other treatment The maximum early and total yield per plant was obtained from the fumigated non fertilized plots.
