“…As the fertilizer level increased from 75% RDF to 125% RDF in drip fertigation the plant height also increased linearly. This finding was in confirmation with Kakade et al, (2017) who concluded that there was a gradual increase in plant height with each increasing level of recommended dose of N and K from 50 to 125 per cent in drip fertigation. Bibi et al, (2011) and Udikeri and Shashidhara (2017) also reported that plant height increased linearly witheach increment of N from 0 to 150 kg/ha.…”

“…Drip fertigation of N and K fertilizers with higher levels of 125 per cent RDNK ha -1 registered their superiority in enhancing all the growth attributes over lower fertigation levels (50, 75 and 100 per cent) and over conventional method of soil application with 100 per cent RDF of NPK (Kakade et al, 2017). Ghule et al, (2013) also noted similar trend in cotton.…”

“…Cotton, the "White Gold" is cultivated in different agro-climatic conditions in India constituting about 62% of the raw material requirement of Indian textile industry. After introduction of Bt cotton under commercial scale, cotton growing area was increased to about 11.84 m ha in 2014-2015 (92% of total cotton area) Kakade et al (2017). Presently India is the second largest producer, consumer and exporter of cotton in the world (Anonymous, 2016).…”

Background: Cotton is one of the important commercial crops cultivated in India for fibre and oil. The average cotton productivity of India is lower compared to other countries. Among the improved agronomic practices, important yield contributing agro techniques are crop geometry and fertilizer application. Drip irrigation and use of water soluble fertilizers (WSF) by drip system is a recommended practice to increase both water and nutrient use efficiency. Taking this aspect, a field investigation was carried out to find the resource use efficiency, productivity and profitability of inter specific Bt cotton hybrid with different levels crop geometry and drip fertigation. Methods: A field experiment was conducted at TNAU, Coimbatore during 2013 and 2014 for two consecutive years. The experiment was laid out in a strip plot design with three replications. The treatments in main plot consisted of four crop geometry levels (120 x 60 cm, 120 x 90 cm, 150 x 60 cm and 150 x 90 cm) and sub plots consisted of four nutrient levels viz., 75 %, 100 %, 125 % of recommended dose as water soluble fertilizer (WSF) through drip system and as conventional practice. Resource use efficiency (water, nutrient), seed cotton yield and profitability of the system were recorded. Result: The experiment revealed that the fertilizer use efficiency and the efficiency of individual nutrient (partial factor productivity) for the crop geometry of 120 x 90 cm and 75% RDF were higher in both the years. The crop geometry of 120 x 90 cm in combination with 125% RDF effectively utilized the water as indicated by its water use efficiency and comparable results was also obtained with 100% RDF. The mean (2012-13 and 2013-14) seed cotton yield of 2,713 kg ha-1 in 120 x 90 cm kg ha-1 for 125% RDF was 41.5 per cent higher compared to their lower counterpart. Their interaction was significant, consequently the treatment M2S3 (120 x 90 cm and 125% RDF) recorded higher mean (both years) seed cotton of 3,176 kg ha-1 which was nearly 93.7 per cent increase over conventional irrigation and fertilizer application (M4S4). Here M1S2 could be considered as alternate option as it maintained similarity with the best treatment. The gross and net return was estimated to be higher with spacing of 120 x 90 cm with 125 % RDF and however the benefit cost ratio was higher with 120 x 90 cm with 100 % RDF followed by 120 x 60 cm with 100 % RDF.

“…Consequently, this situation has led to dependency in intensive agricultural management practices. Fertilizer application is a key farming practice that has been used over a long period of time in improving crop nutrition and productivity through availing of nutrients to plants, with associated soil property and microbial changes [1], and its use is expected to continuously increase in the coming decades. Application of these fertilizers, either organic or inorganic, not only impact on the plants' growth and health, but also influence the soil nutrient availability, physico-chemical properties, plant diseases suppression, disease incidence and soil microbiota [2][3][4].…”

The purpose of the study is to unravel the effects of inorganic Nitrogen (N) combined with either organic fertilizer or biochar on the soil biochemical properties, plant phenotypic characteristics and soil bacterial community structure within an experimental cotton field. The experiment involved the determination of the soil chemical properties, enzymatic activities and bacterial community. The study method employed field measurements, laboratory analyses, high throughput sequencing of the bacterial 16S rDNA to examine the response of soil enzymatic activities, microbial communities and plant phenotypic properties to the applied three different fertilizer regimens; (1) inorganic fertilizer (N), (2) N + organic fertilizer (N + OF), (3) N + biochar fertilizer (N + Biochar), under two cotton varieties: CN01 and ZD2040. The study indicated that combined N plus carbon-based organic fertilizer is responsible for enhanced crop growth, yield productivity and probiotic soil microbial content. Further, the combined mineral and carbon-based fertilizer regimen is highly beneficial to soil microbial content and diversity. The occurrence could be due to the increased soil nutrient content as a result of availability of carbon-based fertilizer and induced microbial activity by the mineral fertilizer. The use of N plus carbon-based organic fertilizer is recommended to improve the soil quality and cotton yield.
